Gitpod: [workspace-image] Update Gradle

[svenefftinge]

We should update the installed gradle to the latest released version.

[rdmueller]

I just tried to work with the currently installed gradle version (4.4.1) but don't succeed.
I can run a

gradle --version

but even a simple

gradle tasks

produces an error which I can't handle:

Picked up JAVA_TOOL_OPTIONS: -Xmx3189m
Starting a Gradle Daemon (subsequent builds will be faster)

FAILURE: Build failed with an exception.

* What went wrong:
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/4.4.1/userguide/gradle_daemon.html
Please read the following process output to find out more:

Something in grade tries to call java.lang.invoke.MethodHandles.privateLookupIn(Class, Lookup) , but that method was introduced in Java9 and we have Java8 installed.

Gradle itself is happy with Java8, according to the docs.

[meysholdt]

workaround: use ./gradlew

[rdmueller]

workaround works - I installed gradle through sdkman.io and initialized the gradle wrapper...

I just wonder if it would make sense to have sdkman.io in the standard container. It lets you easily install various versions of various tools....

[meysholdt]

I just tried sdkman.io in gitpod as well:

1. curl -s https://get.sdkman.io | bash
2. source "/home/gitpod/.sdkman/bin/sdkman-init.sh"
3. sdk install gradle

and gradle -version outputs Welcome to Gradle 5.0!.
I found it because Gradle officially supports it.

It makes sense to use it in the standard container because it can manage Java, Gradle and Maven in the user-space, just as we already do it for node via nvm. Also, it seems to more up-to-date than Debian/Ubuntu apt packages.

[jankeromnes]

I'll look into fixing this in https://github.com/gitpod-io/workspace-images/blob/master/full/Dockerfile directly. Thanks for the sdkman.io suggestion!

[jankeromnes]

I guess we could use either https://sdkman.io or https://linuxbrew.sh here:

• Homebrew seems to be more popular, and does a great job keeping its supported packages up-to-date, but its Linux support is quite recent and I haven't tried it yet.
• On the other hand, SDKMAN seems to be specifically oriented toward Java, Maven and Gradle, so maybe it has better chances of doing a great job there.

I'll do some more research and experiments, but I'm open to suggestions/preferences.

[jankeromnes]

I ran into a few bugs with Linuxbrew, so I went with SDKMAN to install Gradle and Maven.

I'd still like to install Linuxbrew though, because it would allow installing basically any package in Gitpod without sudo.
