Troubleshooting for the Eclipse plugin

Snyk plugins are not supported on any operating system that has reached End Of Life (EOL) with the distributor.

General troubleshooting

For general troubleshooting, see the IDE troubleshooting pages.

Logs

When you enable debug, your code may be logged in the IDE log files, for example, the idea.log file.

To determine where plugin logs are stored, navigate to Preferences > Language Servers > Logs and find the Snyk Language Server row in Eclipse. As the Language Server can be disabled, you may need to enable it to retrieve the logs. You will find the logs either in the console or in the file based on the preference set.

To see additional plugin error logs:

  1. Navigate to Window > Show View > Others....

  2. In type text filer, search for Error Log.

  3. Click Open to see the error log tab. If you group the tab view by plugin (three dots menu in the top right corner > Group By > Plug-in), the io.snyk.eclipse.plugin row shows any plugin errors.

The log level can be set in the Eclipse settings using the environment variable SNYK_LOG_LEVEL , for example,SNYK_LOG_LEVEL=debug.

Determine the installation path of the Language Server, as displayed in the plugin settings. The Language Server logs can be found in the same directory with the file name snyk-ls.log

When working on the terminal, be careful to escape spaces in the folder path.

Proxy settings

Ensure that you read the Snyk Eclipse documentation.

Details to address

  • Determine whether the issue occurs on the CLI terminal, outside of the IDE.

  • Prefereably, use the latest Snyk CLI version.

  • Use the debug option to obtain the user's snyk test and snyk monitor output.

  • Set the proxy variable in the command line: set http_proxy=<http….>

Proxy setting confirmation

In Eclipse, go to Windows → Preferences → General → Network Connections.

Ensure the configured proxy settings are identical to the ones that have been set in the CLI terminal.

The proxy settings can be overridden by adding the settings through the Snyk preferences Additional Environment:

https_proxy=http://your-proxy.com:8080

Issues with installing the Eclipse plugin

If you are facing issues installing Eclipse plugins, it might be due to the incompatibility of the JDK version used by Eclipse. This can be resolved by running Eclipse with JDK 17 or a higher version. Follow these steps:

  1. Download and install JDK 17 or a higher version.

  2. Download and install Eclipse IDE from the official Eclipse website.

  3. After Eclipse IDE is installed, navigate to the Eclipse installation directory and locate the eclipse.inifile.

  4. Open the eclipse.ini file and add the following to it:

    vm {path to JDK 17 or higher version}\bin

    Ensure you replace {path to JDK 17 or higher version} with the actual path where JDK 17 or higher version is installed on your system.

  5. Save and close the eclipse.ini file.

  6. Launch the Eclipse IDE using the usual method.

  7. After Eclipse is launched, go to Window > Preferences > Java > Installed JREs.

  8. Click on Add and select the path to JDK 17 or higher version installed on your system.

  9. Click OK and close the Preferences dialogue box.

You are now ready to install any Eclipse plugin of your choice.

An example follows showing how the eclipse.ini file could look like after adding the path to the JDK 17 or higher version. The last line is the relevant change; the rest of the file, can, but does not need to be touched.

Ensure you replace C:\\\\Program Files\\\\Java\\\\jdk-17.0.1\\\\bin with the actual path where the JDK 17 or higher version is installed on your system.

Application development and JDK version

While running Eclipse with JDK 17 or a higher version can resolve issues related to plugin installation, it is important to note that it may not be compatible with all versions of Java used for developing applications. Depending on the specific requirements of your application, you may need to use a different version of Java, such as JDK 8 or 11, for development purposes. Be sure to consult the documentation and requirements of your application before making any changes to your Java environment.

Note also that while you can install multiple versions of JDK on your system, you can use only one version at a time. This means that if you need to switch between different versions of JDK for different projects, you must update the Eclipse configuration accordingly.

To change the JDK version used by Eclipse for a specific project, follow these steps:

  1. Open the project in Eclipse.

  2. Right-click on the project and select Properties.

  3. In the Properties dialogue box, go to Java Build Path > Libraries.

  4. Locate the JRE System Library and click on it to expand the options.

  5. Click on Edit and select the desired JDK version from the list of installed JREs.

  6. Click Finish to save the changes.

By following these steps, you can easily switch between different JDK versions for different projects in Eclipse. It's important to ensure that you are using the correct version of JDK for each project, as this can impact the compatibility and functionality of your application.

Windows Defender warns of running a binary

Windows Defender can sometimes block or issue warnings when running Go binaries. This can happen for various reasons, for example, the binary may be unrecognized or have behavior that triggers the antivirus software.

To resolve this issue, you can try the following solutions:

  • Add an exclusion: Exclude the Go binary or the directory containing the binary from Windows Defender's scanning. This can help prevent false positives and allow the binary to run without interference.

  • Disable Windows Defender temporarily: If adding an exclusion does not solve the problem, you can temporarily disable Windows Defender while running the Go binary. However, exercise caution when disabling antivirus software and ensure that you have other security measures in place.

  • Submit the binary to Microsoft: If you believe the detection is a false positive, you can report it to Microsoft. They have a process for submitting files to be reviewed, and if confirmed as a false positive, the detection may be updated in future antivirus definitions.

Signing Information for Jars

If you want to verify the correct provenance of your plugin, verify the signing details from the Eclipse dialog using this data.
