Build from source error (Ubuntu 22.04 LTS)
CorbinFoucart opened this issue · comments
Describe the bug
Following the build instructions, npm gradle
generates a versioning incompatibility for JVM
Expected behavior
Following the repo README, I expect the build process to succeed
Additional context
My build script is the following (to create the layout described in the README):
#!/bin/bash
# checkout elkjs
git clone git@github.com:kieler/elkjs.git
# checkout ELK
git clone git@github.com:eclipse/elk.git
cd elkjs
npm install
npm run build
which fails with
> elkjs@0.10.0 build
> npm run gradle && npm run js
> elkjs@0.10.0 gradle
> ./gradlew lib
FAILURE: Build failed with an exception.
* Where:
Build file '/path/to/elkjs_from_source/elkjs/build.gradle'
* What went wrong:
Could not compile build file '/path/to/elkjs_from_source/elkjs/build.gradle'.

when I check the versioning:
$ ./gradlew --version

Gradle 7.2

Build time: 2021-08-17 09:59:03 UTC
Revision: a773786b58bb28710e3dc96c4d1a7063628952ad
Kotlin: 1.5.21
Groovy: 3.0.8

JVM: 21.0.2 (Private Build 21.0.2+13-Ubuntu-122.04.1)
OS: Linux 6.5.0-21-generic amd64
For those who encounter a similar issue, Gradle 7.2 is incompatible with JVM 21. Setting the bash environment to point to a JVM installation lower than 17 allowed the build to proceed.
$ export JAVA_HOME=/path/to/java-11-openjdk-amd64
$./gradlew --version
