Upgrading my plugins to 2021.*/Gradle java.lang.NoClassDefFoundError: com/intellij/openapi/compiler/CompileTask
Answered
Hi All
After ugrading all my plugins to 2021.* and using gradle, I have this problem:
This code
import com.intellij.openapi.compiler.CompileTask;
is compiled successfully, but on runtime I get
java.lang.NoClassDefFoundError: com/intellij/openapi/compiler/CompileTask
So I added
<depends>com.intellij.java</depends>
And it solves the problem, But I did it without understand why, what is the principle ?
com.intellij.openapi.compiler.CompileTask is part of the openapi, How can I guess that com.intellij.java is needed ? How do I know for other used classes what plugin is needed ?
Thanks

Hi, Boaz!
This class belongs to the Java module – you can easily verify it by looking at the intellij-community sources:
https://github.com/JetBrains/intellij-community/blob/master/java/compiler/openapi/src/com/intellij/openapi/compiler/CompileTask.java
Note, the leading /java/compiler/openapi
So, to make your plugin working, you have to set the dependency to Java module both in the Gradle configuration, as well as plugin.xml.
For more information, please check the Modules Specific to Functionality docs page.
Thank!!!
