'Gradle error: Could not initialize class org.codehaus.groovy.runtime.InvokerHelper

I need to see my dependencies in Gradle to fix a problem with multiple SLF4J bindings.
However, when I run 'gradle dependencies' I get the error:

Could not initialize class org.codehaus.groovy.runtime.InvokerHelper

In a similar question in stack-overflow Android Studio Could not initialize class org.codehaus.groovy.runtime.InvokerHelper
it was recommended to

  1. install java jdk-14
  2. upgrade to gradle version 6.3

I changed the jdk to 14 in IntelliJ in 2 places:

  1. File -> Project Structure -> Project -> Project SDK
  2. Preferences -> Gradle -> Gradle JVM

I attempted to update gradle from the command line with: 'gradle wrapper --gradle-version 6.3' and got the same error:

Could not initialize class org.codehaus.groovy.runtime.InvokerHelper

I then changed the field 'distributionUrl' in the file 'gradle-wrapper.properties' to 'gradle-6.3', as instructed here https://github.com/gradle/gradle/issues/10248.

I tried various combinations of jdk and gradle versions but nothing seems to work.

So from your repo, if you have gradle-wrapper.properties like this:

? cat gradle/wrapper/gradle-wrapper.properties
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-6.3-bin.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

On first compilation, Gradle tells you that:

  build file '/Users/tim/Code/Java/brobotREST/build.gradle': 36:
     all buildscript {} blocks must appear before any plugins {} blocks in the script

So if you move the buildscript section up to the top of the build.gradle file, it all seems to work

And I get:

? ./gradlew -version

Had a similar problem on Windows 10 caused by a java version issue. In build.gradle set the java source compatibility flag; For java 1.8 this is

sourceCompatibility = '1.8'

then check the system version is the same

java -version

I had a similar problem on macOS. It seems, it was a problem with version difference by IntelliJ IDEA and Gradle. I adjusted the Gradle version in /gradle/gradle-wrapper.properties. In my case I have set: distributionUrl=https\://services.gradle.org/distributions/gradle-6.6.1-bin.zip

and now it works. See also Gradle: Could not initialize class org.codehaus.groovy.runtime.InvokerHelper
