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
- install java jdk-14
- upgrade to gradle version 6.3
I changed the jdk to 14 in IntelliJ in 2 places:
- File -> Project Structure -> Project -> Project SDK
- 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.
Answer
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 ------------------------------------------------------------ Gradle 6.3 ------------------------------------------------------------ Build time: 2020-03-24 19:52:07 UTC Revision: bacd40b727b0130eeac8855ae3f9fd9a0b207c60 Kotlin: 1.3.70 Groovy: 2.5.10 Ant: Apache Ant(TM) version 1.10.7 compiled on September 1 2019 JVM: 14 (Azul Systems, Inc. 14+36) OS: Mac OS X 10.15.4 x86_64
