Otherwise, it's impossible to use Dev Build for branches that don't have MultiRoutingFileSystemProvider, like the branch 241. GitOrigin-RevId: 247b84e22b2734f2541983df7cef886b7ec4b82d
Plugin DevKit Implementation Notes
Inspections
See org.jetbrains.idea.devkit.inspections.DevKitInspectionUtil for common utility methods.
Consider marking inspections with safe-only fixes ready for Code | Code Cleanup...
(com.intellij.codeInspection.CleanupLocalInspectionTool).
Inspections should avoid running whenever they are not applicable in the current context.
Add projectType="INTELLIJ_PLUGIN" in plugin.xml registration to avoid loading inspection in non-plugin projects.
Additional contexts include:
- requires minimum platform version (
org.jetbrains.idea.devkit.util.PluginPlatformInfo) - requires present platform API class (only available in newer platform versions). It is safe to assume most plugins do not target the latest platform.
- requires present plugin API class (e.g., checks specific to Java PSI)
- checked class is not a suitable candidate (e.g., a class without FQN cannot be registered in
plugin.xml) - only applicable to IDEA project (
org.jetbrains.idea.devkit.util.PsiUtil.isIdeaProject())
Code: JVM Languages
Use org.jetbrains.idea.devkit.inspections.DevKitUastInspectionBase or org.jetbrains.idea.devkit.inspections.DevKitJvmInspection.
See their docs for important considerations.
Implement and register in intellij.devkit.core module.
See Testing Code: JVM Languages.
Code: Kotlin Only
Use regular LocalInspectionTool with immediate DevKitInspectionUtil.isAllowed(holder.file) check to skip running in non-plugin context.
Implement and register in intellij.kotlin.devkit module.
Plugin Descriptor
Extend org.jetbrains.idea.devkit.inspections.DevKitPluginXmlInspectionBase and override checkDomElement() to check specific DOM
elements.
See Testing: Plugin Descriptor
Tests
Use light tests only ideally.
See existing base classes like org.jetbrains.idea.devkit.inspections.PluginModuleTestCase
or org.jetbrains.idea.devkit.inspections.quickfix.LightDevKitInspectionFixTestBase.
Add required classes in the test as "mock" containing the minimum set of required signatures.
Same for declaring platform extension points, declare them in testdata plugin.xml.
Testing Code: JVM Languages
Always write explicit tests for both Java and Kotlin sources.
Tests and test data go to intellij.devkit.java.tests and intellij.devkit.kotlin.tests, respectively.
Related plugin.xml can be put on same level as code test data files.
Test data path constants: org.jetbrains.idea.devkit.DevkitJavaTestsUtil & org.jetbrains.idea.devkit.kotlin.DevkitKtTestsUtil.
Testing: Plugin Descriptor
Extend from org.jetbrains.idea.devkit.inspections.PluginXmlDomInspectionTestBase.
