Last updated
After completing this unit, you'll be able to:
These step-by-step instructions will show you how to install the CodeScan plugin.
Click the CodeScan icon on the left panel.
Click on ‘Add CodeScan Connection.’
Add your CodeScan URL.
Click on 'Generate Token.' This will open CodeScan in a browser.
Click 'Allow Connection' to send the newly generated token back to your IDE.
Add your organization key.
Enter a Unique Connection Name.
Click on 'Save Connection.' You will see your connection appear in your connected mode window.
Click on your connection (CodeScan Cloud in the example.)
Click the + symbol to the right. This will show you a list of projects from the Command palette.
Select the project you would like to connect to.
The project you connect to determines the rules for scanning your open files.
Note: If the project you have open in VS Code matches the project you connect to in CodeScan Cloud, your IDE scans will ignore any Won’t Fix or False Positive issues.
The CodeScan VS Code extension provides immediate feedback to developers on bugs and quality issues; it is a fully integrated user experience in Visual Studio Code (we'll refer to it as VS Code).
Make sure you:
Install the latest VS Code version.
Have a CodeScan cloud account:
Have a valid enterprise license (or a cloud trial version—trial not available with self-hosted)
For CodeScan Self Hosted:
Have a working SonarQube™ (9.9+) server
Have a licensed version (no trial available) of the latest CodeScan plugin to get started (more info).
Download the CodeScan extension from the marketplace
Download the Salesforce Extension pack from the marketplace if you are working with Salesforce code or, at a minimum, the Visualforce plugins.
Install JDK version 17 or above.
Install Java Runtime (JRE) 17 version or later.
Install the latest available Node.js LTS version.
Uninstall the Apex PMD and SonarLint™ plugins. The CodeScan and VS Code plugin will not work with SonarLint™ or Apex PMD installed.
Version 2.0.0 requires Java Runtime (JRE) / JDK versions 17 or later. Prior CS versions will still work with older JRE / JDK versions 11.
Note: CodeScan plugin is designed to work with a single VS Code window at a time. Using the CodeScan plugin while having multiple VS Code windows open may give unexpected results.
Follow the installation instructions for the CodeScan extension and bind the extension to your CodeScan server.
Step 1: Install CodeScan for VS Code Extension
Open Visual Studio Code and go to the Activity Bar on your left. The last button on the Activity Bar is the Extensions button.
Note: You can also press the Shortcut Key combination Ctrl + Shift + X
to launch the Extensions side panel.
Search for CodeScan and click on Install to install the CodeScan latest extension, preferably version 1.6.8 or above.
Once installed, restart or reload VS Code to ensure it's taken effect.
Step 2: Java Runtime (JRE) 11 Installation
CodeScan should automatically find the JRE installed on your computer. Or you can specify the JRE path on your VS Code's Settings page by navigating to VS Code Settings > Settings > Extensions > CodeScan.
Under CodeScan > Ls: Java Home (Not synced), enter the JRE path.
Next, confirm the JAVA_HOME variable is set properly on your system. Enter the command echo %JAVA_HOME%. This should output the path to your Java installation folder. Reach out to your IT department if the JAVA_HOME variable is not set.
Step 3: Generate CodeScan token
You can generate new tokens at User > My Account > Security or use an existing token if you have one saved. Copy the generated token and add it to the settings.json file (discussed later).
Step 4: Obtain the Project Key
Log in to CodeScan, click on the Projects tab, and find the project you need to configure. Click on the Project Information tab to find your project key at the bottom right of your screen.
Step 5: Obtain the Organization Key
You can always find your organization key at the top right of your **organization **home page.
Step 6: Add CodeScan Configuration
Press Ctrl + Shift + P in the VS Code, and search for Settings and select Open User Settings (JSON).
On the settings.json tab, inside the curly braces ({ }), copy and paste the following text, and add the parameters shown in the table below:
Example:
PARAMETER | DESCRIPTION |
---|---|
serverID | Add serverId with a value you will remember. You will need to enter the same value in both of the serverId parameters. |
Add your CodeScan organization key. If you are using CodeScan Self-Hosted, enter your default-organization. | |
serverUrl | For CodeScan Cloud, enter: https://app.codescan.io/for U.S. region, https://app-eu.codescan.io/ for EU, and https://app-aus.codescan.io/for AUS. |
For Self-Hosted CodeScan, add serverUrl as your SonarQube™ server URL (default is http://localhost:9000). | | token | Add your security token. For Self-Hosted CodeScan, add token generated in SonarQube™. | | cell | Add your CodeScan project key.| | codescan.httpclient.version | (applicable for VS Code v1.6.10 or later) | Enter the Apache HTTP client protocol version (FORCE_HTTP_1, FORCE_HTTP_2, or NEGOTIATE). |
Note: If no protocol version is set, the default protocol is NEGOTIATE.
Save the settings.json file.
Step 7: Configure the Project Binding
Next, you will need to update the CodeScan bindings for the workspace to ensure the rules are in sync.
Select - Shift+Command+P or - Shift+Command+P (Mac) to open the Command Palette. Type in CodeScan to bring up the CodeScan commands and run Update CodeScan binding to SonarQube/CodeScan Cloud.
An All CodeScan bindings successfully updated notification appears once the binding is completed successfully.
Step 8: Verifying
You can verify this by opening a file that has problems. They will now be highlighted within your code:
An underline shows a pop-up of the issue when hovering
Within the VS Code problems panel
Once you're done installing the CodeScan extension from the marketplace,
Restart the Visual Studio Code.
Press Ctrl + Shift + P
and search for Settings
and select Open User Settings (JSON).
On the settings.json tab, inside the curly braces ({ }), copy and paste the following text:
Plain text Copy
Parameters | Description |
---|---|
serverId | Add serverId with a value you will remember. You will need to enter the same value in both of the serverId parameters. |
Add your CodeScan organization key. If you are using CodeScan Self Hosted, please enter your default-organization. | |
serverUrl | For CodeScan cloud, please enter:
|
Add your security token. For Self-Hosted CodeScan, add token generated in SonarQube™. | |
Add your CodeScan project key. | |
codescan.httpclient.version (applicable for VS Code v1.6.10 or later) | Enter the Apache HTTP client protocol version ( |
Save the settings.json file.
Now select Ctrl+Shift+P (Windows/Linux)
or Shift+Command+P(Mac)
to open the Command Palette.
Type in CodeScan
to bring up the CodeScan commands and run Update CodeScan binding to SonarQube/CodeScan Cloud
.
Go to View > Output to view the logs details. If a problem does occur, you are able to trace it via logs.
Select Terminal > New Terminal
or press Ctrl+Shift +`, if you are not able to view the Output section at the bottom of the screen.
An All CodeScan bindings successfully updated
notification appears if the binding is successfully completed.
If any changes are made on the SonarQube™ server, then repeat this step.
Open a file, and you should see the issues in your code underlined.
VS Code extensions can be difficult to use behind a proxy. To point CodeScan at the correct proxy, all it takes is a single environment variable for your system.
The environment variable is: JAVA_TOOL_OPTIONS
Follow the steps to set environment variables using the Windows GUI:
Press Windows + R
to open the Windows Run prompt.
Type in sysdm.cpl
and click OK
.
Open the Advanced
tab and click on the Environment Variables
button in the System Properties window.
The Environment Variables window is divided into two sections. Click the New…
button on the top section.
In the New User Variable prompt, enter the Variable Name
as JAVA_TOOL_OPTIONS,
enter the following Variable Value
, and click OK
.
Variable Value:
If the proxy has a username and password, you can add/update the following parameters and add them at the end of the variable value field.
If you are connecting to a server with self-signed certificates, you will need to specify them for your Java and Node installations.
For your Java installation, you can find the documentation here.
For Node installation, add the environment variable NODEEXTRACA_CERTS
with the path to your certificate file as a value, e.g., /usr/local/share/ca-certificates/YOUR_CERT.crt.
Error Code:
Reason: This error occurs when the Java environment does not trust the certificate of the server running your SonarQube instance.
Solution: Install the server certificate to the Java key.
Steps:
Click on this icon and a window will pop up. From the window, select Connection is secure.
Select the second option, i.e., Certificate is valid
.
Go to the Details tab and click on Export.
Rename the certificate (e.g., codescan-certificate), then choose a location and save the certificate.
The next process is to install the certificate in the cacerts file of the jdk installed in the system using the command line.
Command:
keytool -import -alias {alias-name for the certificate} -keystore “{path for the cacerts file}” -file {path where we have save the certificate}
Example:
keytool -import -alias codescan-certificate -keystore "C:\Program Files\Java\jdk-11.0.9\lib\security\cacerts" -file c:/tmp/codescan-certificate.crt
When adding the certificate, password is required. The password is changeit
.
Point to Note:
If adding the certificate as a trusted certificate to the Java Keystore still results in the PKIX path building failed error, we suggest you delete the currently installed certificate from the Java Keystore, export a new certificate, and then attempt a new installation of the certificate.
Command to list all of the certificates from the Java Keystore: keytool -list -v -keystore “{path for the cacerts file}” > /tmp/certs_list.txt
Example: keytool -list -v -keystore “c:\Program Files\Java\jdk-11.0.13\lib\security\cacerts” > /tmp/certs_list.txt
Command to delete the certificate: keytool -delete -noprompt -alias {alias-name for the certificate} -keystore “{path for the cacerts file}”
Example: keytool -delete -noprompt -alias codescan-certificate -keystore “c:\Program Files\Java\jdk-11.0.13\lib\security\cacerts”
If the CodeScan update binding is getting failed, try disabling the VPN and antivirus, then try updating the binding again.
If the binding successfully updates, the error occurred due to antivirus blocking CodeScan. Add CodeScan to the list of allowed sites for the antivirus in use.
If the binding still fails, check the HTTP client protocol version. Enter the Apache HTTP client protocol version (FORCE_HTP_1, FORCE_HTTP_2, or NEGOTIATE). Save and Update Bindings. Further documentation is available here in the 'Parameters' section.
If the binding still fails, raise a Support Ticket, including the analyzer logs and verbose logs in the attachment.
If Apex PMD plugin is installed alongside the CodeScan plugin, one or more of the following issues may occur:
CodeScan is not listed in the dropdown in Output Tab
of VS Code terminal.
Inconsistency in the number of issues for a file on saving the file.
Problems for a specific file are displayed even when the file is closed.
All these issues can be resolved by uninstalling Apex PMD plugin and restarting IDE, then updating the Binding to CodeScan Cloud.
CodeScan should automatically find the JRE installed on your computer. If you have trouble, then you can specify the JRE path on your VS Code's Settings page.
Navigation: VS Code Settings > Settings > Extensions > CodeScan.
Under CodeScan > Ls: Java Home (Not synced), enter the JRE path.
You can click on the summary or press Ctrl+Shift+M
to display the PROBLEMS
panel with a list of all current errors. If you open a file that has errors or warnings, they will be rendered inline with the text and in the overview ruler.
Note: The VS Code displays the code issues related to bugs, vulnerabilities and code smells inside the PROBLEMS
tab. No code-duplications are shown in the IDE.
Some useful debugging information is available under the Output
window under the ‘CodeScan
’ tab.
Also, you can check for any serious errors by going to Help > Toggle Developer Tools
to bring up the console.
v. 2.0.3
Changes were required to support fixes and enhancements of the VS Code CodeScan Plugin (v2.0.3) to VS Code Extension Marketplace; specifically, we fixed a plugin issue that caused non-recognition of CodeScan-specific JS and VF rules.
13 June 2024
v. 2.0.2
New CodeScan Issue Filter: Quickly sort and filter issues by type and severity for efficient code review. You can click on the specific Type or Severity to only see issues of that type.
The released plugin can be updated directly from VSCode and also can be found in this link: https://marketplace.visualstudio.com/items?itemName=codescansf.codescan-vscode
Before raising a support ticket, perform the following checks in VS Code:
Is the Sonarlint or ApexPMD plugin installed alongside CodeScan? If so, uninstall it.
Is the Salesforce extension pack installed in VS Code? If not, install, as this is mandatory.
What version of Java is installed? Version 2.0.0 onward requires Java Runtime (JRE) / JDK versions 17 or later. Prior CS versions will still work with older JRE / JDK versions 11.
Is the Java path passed to CodeScan (codescan.ls.javaHome)? Verify by going to VS Code Settings > Settings > Extensions > CodeScan
and under Codescan › Ls: Java Home (Not synced),
you should see the JAVA_HOME
path mentioned. If not present, please enter the JAVA_HOME
path.
You can also add the JAVA_HOME
path in the settings.json file inside the codescan.ls.javaHome
property.
Perform the CodeScan Update Binding and check if the issue is resolved.
NOTE: Duplicate lines of code and Security Hotspot issues do not show up in IDE.
