configuration classpath for gradle in eclipse or vscode redhat java
Configuring the classpath for a Gradle project in Visual Studio Code (VSCode) involves specifying the dependencies and build settings.
Here’s a guide for both IDEs:
Search java source
Searching source configs inside .classpath
and *.prefs
files
- Search java source config by substring
path="src/main/java"
- Replace output attribute to gradle build folder
output="build/classes/java/main"
result looks like:
<classpathentry excluding="**/*.txt" output="build/classes/java/main" kind="src" path="src/main/java">
<attributes>
<attribute name="gradle_scope" value="main"/>
<attribute name="gradle_used_by_scope" value="main,test"/>
</attributes>
</classpathentry>
<classpathentry output="build/classes/java/test" kind="src" path="src/test/java">
<attributes>
<attribute name="gradle_scope" value="test"/>
<attribute name="gradle_used_by_scope" value="test"/>
<attribute name="test" value="true"/>
</attributes>
</classpathentry>
- Search annotation config
bin/generated-sources/annotations
andbin/generated-test-sources/annotations
- Replace with
build/generated/sources/annotationProcessor/java/main
andbuild/generated/sources/annotationProcessor/java/test
- Verify all output directory are configured by searching subtring
bin/
for.classpath
and*.prefs
files

</classpathentry>
<classpathentry kind="output" path="build/default"/>
</classpath>
Configure .vscode/settings.json
- In the
.vscode
directory (created by the above task), there should be asettings.json
file. - Ensure it has the necessary classpath settings.
Example settings.json
:
{
"java.project.outputPath": "build",
"java.import.generatesMetadataFilesAtProjectRoot": false,
"java.editor.reloadChangedSources": "auto",
"java.configuration.updateBuildConfiguration": "disabled",
"java.server.launchMode": "Hybrid",
"java.project.referencedLibraries": [
"build/classes/java/main",
"build/resources/main",
"lib/**/*.jar"
],
"java.edit.smartSemicolonDetection.enabled": true,
"terminal.integrated.env.windows": {
"PATH": "${workspaceFolder};${workspaceFolder}\\bin;${workspaceFolder}\\node_modules\\.bin;${env:PATH}"
},
"terminal.integrated.env.linux": {
"PATH": "${workspaceFolder}:${workspaceFolder}/bin:${workspaceFolder}/node_modules/.bin:${env:PATH}"
},
"java.sharedIndexes.enabled": "off",
"java.project.resourceFilters": [
"node_modules",
"\\.git",
"\\.cache"
]
}
Conclusion
Now you don’t have to wait long when opening a Java project in VScode with the Redhat Java plugin, because all build output is synchronized from Gradle and Eclipse JDT which are used by the Redhat Java extension.
And this trick can change the output folder from Redhat Java Extension to the Gradle build folder.
