eclipse gradle Could not run phased build action

Question

I am trying to run some gradle project on windows using eclipse. it is rapid miner extension template. but eclipse keeps showing this error:

Could not run phased build action using connection to Gradle distribution 'https://services.gradle.org/distributions/gradle-7.1.1-bin.zip'.

com.google.common.util.concurrent.ExecutionError: java.lang.NoClassDefFoundError: org/gradle/api/internal/java/JavaLibrary java.lang.NoClassDefFoundError: org/gradle/api/internal/java/JavaLibrary org/gradle/api/internal/java/JavaLibrary org.gradle.api.internal.java.JavaLibrary

i tried different gradle versions and different configs. but it keeps showing this error. i need to fix this.

Answer 1

What gradle task did you try to run?

The extension template is used to create new extensions for RapidMiner Studio.

A detailed guide how to use it is found here: https://docs.rapidminer.com/latest/developers/extensions/

So your first step should be to adapt the build.gradle file and then run the initializeExtensionProject task.

Afterwards you can write your Java code to build a new RapidMiner operator for example and then run the installExtension task to install the new extension on your local version of RapidMiner Studio.
