Gradle build fails with "java.lang.NoClassDefFoundError: org/gradle/api/plugins/MavenPlugin"

[TAGC]

I've recently tried cloning and building this library, but I've found that I'm unable to build it using either the Gradle wrapper or a locally-installed version of Gradle.

I first tried installing via the Gradle wrapper (./gradlew clean build), but it failed with this error:

> startup failed:
  General error during semantic analysis: Unsupported class file major version 61

The documentation recommends to build the library by running gradle clean build (i.e. a locally-installed instance of Gradle), so I'll focus on that for this issue. The steps below reflect my attempt to build this library on macOS with no prior version of Gradle installed.

Steps To Reproduce

1. Run git clone https://github.com/aws/aws-msk-iam-auth.git
2. Run brew install gradle
3. Run gradle clean build --stacktrace

Output

Running the last step produces the following output:

FAILURE: Build failed with an exception.

* What went wrong:

[andrewmslack]

same, what is the status of this?

[pbacellar]

Also getting this with releases 1.1.6 and 1.1.5. Didn't test the others. Lowering gradle version only gave me different errors. Honestly, I have no clue what to do. Tried JDK 20 and 17, with Java 20, gradle 8.1.1, 7.6, 7.5. What is going on?

[safwank]

FYI I managed to resolve this by using Java 11.

[rohitm53]

Same issue with gradle
Java version : 17
gradle wrapper version 8.5
Is anyone able to fix this ?

[alantang888]

I using Mac. And using brew gradle@6 with OpenJDK 11 can solve this issue.
Brew was installed gradle 8.5 when using brew install gradle.

[emorneau]

This worked for me (thanks for the indication to run with the gradle downgrade version 6):
java --version
java 20.0.2 2023-07-18
Java(TM) SE Runtime Environment (build 20.0.2+9-78)
Java HotSpot(TM) 64-Bit Server VM (build 20.0.2+9-78, mixed mode, sharing)

brew install gradle@6
/usr/local/Cellar/gradle@6/6.9.4/bin/gradle clean build

[Estomihi21]

Same issue with gradle Java version : 17 gradle wrapper version 8.5 Is anyone able to fix this ?

same here, did you already solve it?

[naris]

Try using gradle 7.6.3

[balosh-daniel]

just for reference, this works

docker run --platform linux/amd64 --rm -u gradle -v "$PWD":/home/gradle/project -w /home/gradle/project gradle:6-jdk11-alpine -- gradle clean shadowJar --stacktrace --info

[kpamansoor]

I am also facing same issue on gradle 8.0.

[froshyfrosh]

Regarding this error message:
java.lang.ClassNotFoundException: org.gradle.api.plugins.MavenPlugin

As far as I know (now) the old maven plugin was finally removed, so if that is still used instead of the maven-publish plugin it will fail (no matter what Java version is used). In my case it was indirectly used by another plugin (shadow) where I had to switch to the latest version.

https://docs.gradle.org/current/userguide/upgrading_version_6.html#removal_of_the_legacy_maven_plugin
says it has been removed already in Gradle 7 but for me it was working in Gradle 7 and only failed when I was trying to switch to Gradle 8 in several projects (maybe there was a special mode for that case where the maven plugin was only indirectly used by another plugin?).

Same, spring-boot for me I think, works in gradle 7 but not 8
