Jenkins – Could not find GradleWrapperMain

Create a Gradle project in Jenkins CI, source management with Git, and build with Gradle Wrapper

1. Problem

Jenkins console output, the build is failed – “Could not find org.gradle.wrapper.GradleWrapperMain

[Gradle] - Launching build.
[workspace] $ /var/lib/jenkins/jobs/GradleTest/workspace/gradlew clean test

Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain

Build step 'Invoke Gradle script' changed build result to FAILURE
Build step 'Invoke Gradle script' marked build as failure
Finished: FAILURE

2. Solution

2.1 The class GradleWrapperMain is inside the gradle-wrapper.jar, and Jenkins is unable to find it. I believe you forgot to check in the generated gradle-wrapper.jar

2.2 To fix it, create a Gradle wrapper again, and make sure the following files and folders are added to your version control system like GitHub.

|---gradle
    |---wrapper
        |---gradle-wrapper.jar
        |---gradle-wrapper.properties
|---gradlew
|---gradlew.bat 

Done.
