"Could not run phased build action using connection to Gradle distribution"

Question

I'm having various Gradle problems after a new clean Eclipse install. They seem to be associated w/ this "Problem" message:

Could not run phased build action using connection to Gradle distribution 'https://services.gradle.org/distributions/gradle-7.1.1-bin.zip'.
Initialization script 'Z:\eclipse-workspace\.metadata\.plugins\org.eclipse.buildship.core\init.d\eclipsePlugin.gradle'
Could not compile initialization script 'Z:\eclipse-workspace\.metadata\.plugins\org.eclipse.buildship.core\init.d\eclipsePlugin.gradle'.
startup failed:
General error during semantic analysis: Unsupported class file major version 60

I've already tried deleting .gradle & "Gradle->Refresh Gradle Project". I've also tried this: stackoverflow

My Java install is clean:

java version "16.0.1" 2021-04-20

& confirmed Eclipse is pointing to it ("Preferences->Java->Installed JREs").

Installation details:

Buildship: Eclipse Plug-ins for Gradle  3.1.5.v20210113-0929
Eclipse IDE for Java Developers 4.20.0.20210612-1200

Windows 10.

Eclipse Install Err Log:

!MESSAGE Initialize project testgradleprj failed due to an error in the referenced Gradle build.

Gradle 6.8 does not work with Java 16.
Java 16 supported starting with Gradle 7

"In previous Gradle versions, running Gradle itself on Java 16 resulted in an error."

I changed the Gradle version to 7.1.1 in the Preferences->Gradle. Same problem. – JDOaktown Jul 09 '21 at 22:28

OK, it's working now. I created another test gradle project. build.gradle file now included and "Add Gradle Nature" now working. – JDOaktown Jul 09 '21 at 23:06
Nice, you can accept the answer if you agree :-) – LMC Jul 09 '21 at 23:08

@JDOaktown if your gradle is in offline mode and you try to add a dependency then you'll get this useless ass error message which does a terrible job describing the actual error. – Cardinal System Oct 16 '21 at 23:11

You could also try [upgrading the wrapper](https://docs.gradle.org/current/userguide/gradle_wrapper.html). – LMC Jul 09 '21 at 23:19
Thanks. I saw this but couldn't figure out how to apply it against Eclipse. I right-clicked the "wrapper" task in the Gradle Tasks button but still not clear. – JDOaktown Jul 09 '21 at 23:29

OK. I did the following: Z:\eclipse-workspace\gradleprj4>.\gradlew wrapper --gradle-version 7.1.1 BUILD SUCCESSFUL in 1s 1 actionable task: 1 up-to-date – JDOaktown Jul 09 '21 at 23:37

Eclipse will respect the wrapper in the project I think. – LMC Jul 09 '21 at 23:37
