"gradlew buildBwcVersion" fails with misleading error if JAVA11_HOME is not set #37586
Description
Elasticsearch version (bin/elasticsearch --version): build issue, seen with master branch
Plugins installed: []
JVM version (java -version):
openjdk version "11.0.1" 2018-10-16
OpenJDK Runtime Environment (build 11.0.1+13-Ubuntu-2ubuntu1)

Description of the problem including expected versus actual behavior:
When I run buildBwcVersion, it fails with ERROR: JAVA_HOME is set to an invalid directory: null, but JAVA_HOME is set. It's actually JAVA11_HOME that's missing.
Steps to reproduce:
- Confirm that
JAVA_HOMEis set, butJAVA11_HOMEis not (env | grep JAVA) - Check out the latest source and confirm that Java 11 is set in java-versions.properties (
grep 11 .ci/java-versions.properties) - Run
./gradlew buildBwcVersion. The build should fail withERROR: JAVA_HOME is set to an invalid directory: null.
Provide logs (if relevant):
