Preparing the extension template, issue with gradle

Can't initialize the project:

./gradlew --no-daemon initializeExtensionProject

I get this error:

To honour the JVM settings for this build a single-use Daemon process will be forked. See https://docs.gradle.org/6.8/userguide/gradle_daemon.html#sec:disabling_the_daemon.

Daemon will be stopped at the end of the build

FAILURE: Build failed with an exception.

* What went wrong:

com.google.common.util.concurrent.ExecutionError: java.lang.NoClassDefFoundError: org/gradle/api/internal/java/JavaLibrary

> java.lang.NoClassDefFoundError: org/gradle/api/internal/java/JavaLibrary

Also, on eclipse I get this error:

Could not run phased build action using connection to Gradle distribution 'https://services.gradle.org/distributions/gradle-6.8-bin.zip'.

com.google.common.util.concurrent.ExecutionError: java.lang.NoClassDefFoundError: org/gradle/api/internal/java/JavaLibrary

I don't know what to do here, could someone help please?

Hi @gmeier

I believe now both my java and gradle versions are correct:

When I try to initialize, I get this error:

Hi @anaRodrigues
It seems there was a problem with our dependency management and this was fixed in our maven on Friday. You might have to clear your maven cache for the RapidMiner Studio artifact, but now it should work.

Cheers

Hi @anaRodrigues,

are you using the extension template from https://github.com/rapidminer/rapidminer-extension-template? I am a bit puzzled that this is using gradle 6.8 for you; when running 'gradlew -version' this leads to a 4.6 version for me. Just executing 'gradlew --no-daemon initializeExtensionProject' in the folder which contains the README.md should work. The error you quoted could be caused by a wrong gradle version, so try to ensure that you are using a 4.x version. We are working on making the extensions compatible with gradle 6 but that template has not been adjusted yet.

anaRodrigues

Hi @gmeier,

You are right, I had changed the gradle version to match the one I have installed. I did everything from the beginning without changing anything and still got an error. I will try downgrading the gradle version on eclipse.

Description Resource Path Location Type

Could not run build action using connection to Gradle distribution 'https://services.gradle.org/distributions/gradle-4.6-bin.zip'.

Unable to start the daemon process.

This problem might be caused by incorrect configuration of the daemon.

For example, an unrecognized jvm option is used.

Please refer to the user guide chapter on the daemon at https://docs.gradle.org/4.6/userguide/gradle_daemon.html

Please read the following process output to find out more:

Thank you,

Hi @anaRodrigues,

you can also try without the --no-daemon, that should work, too. Maybe that helps already.

If it does not work with eclipse, just go to the folder and run it in the command line:

(also works with --no-daemon but then there is no popup and instead you need to enter Y)

Hi @gmeier,

Still not working (from command line):

Hi @anaRodrigues,

we are making progress

Now you need a java 8 version for gradle.

You can check with 'gradlew -version', there the JVM should be 1.8.

You can either point your JAVA_HOME environment variable to a jdk 8 or try to use org.gradle.java.home=/path_to_jdk_directory in the gradle.properties.

anaRodrigues

Hi @gmeier,

This is where my JAVA_HOME is pointing:

Image: https://us.v-cdn.net/6030995/uploads/editor/sb/z3mb8wsapmgz.jpg

Also, my java version:

PS C:\> javac -version
javac 15.0.2

The gradlew -version command is not recognized.

PS C:\> gradlew -version
gradlew : The term 'gradlew' is not recognized as the name of a cmdlet, function, script file, or operable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ gradlew -version
+ ~~~~~~~
    + CategoryInfo          : ObjectNotFound: (gradlew:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

I have the GRADLE_HOME environment variable set, so I don't know why the command is not working.

Image: https://us.v-cdn.net/6030995/uploads/editor/nv/ic0x0yt4pjt4.jpg

I have also downgraded my gradle version to this 4.6

However, if I ask for the gradle version:

PS C:\> gradle -version

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine java version from '15.0.2'.

* Try:

* Get more help at https://help.gradle.org

I get the same error as before.

Sorry for the trouble and thank you,
Ana

gmeier

Hi @anaRodrigues,
yes, that means you have Java 15, but you need 8. You can for example download it from here and then point your JAVA_HOME to it.
For the 'gradlew -version' command, you need to go to your extension-template folder and execute it there.
