Hi community members, I'm trying to contribute to ES but when I run `./gradlew check` to validate tests before writing any codes, I have the following error: To honour the JVM settings for this build a new JVM will be forked. Please consider using the daemon: [The Gradle Daemon - Gradle User Manual](https://docs.gradle.org/4.9/userguide/gradle_daemon.html).

Some of the tests require running on specific versions of Java. For example, in the first error, we want to test reindexing from Elasticsearch v0.9, v1 and v2, but those versions of ES only ran on Java 7, so it is not possible for those tests to complete unless you have a Java 7 VM. The build requires that you have environment variables named - `JAVA7_HOME` - `JAVA8_HOME` - `JAVA10_HOME` that point to their respective Java installations in order to run those tests. Our development docs _ought_ to explain this, but don't. Perhaps your first contribution could be a PR to add that information to the CONTRIBUTING doc. ---

Unfortunately, I set the env variables but they don't seem to work. ☹ ---

I suspect that you haven't set them up correctly, as this is same build process that all the Elasticsearch development team uses. Can you show more details about how you set these variables? Did you `export` them for child processes? ---

I think I remember something about this. Could you try setting your JAVA\_HOME to JAVA8\_HOME and running the build? I remember reading somewhere about the js scripts that we use early in the build being trouble. ---

No, it doesn't work either. Now it's complaining about the JDK version > Configure project :benchmarks > ======================================= > Elasticsearch Build Hamster says Hello! > ======================================= > Gradle Version : 4.9 > OS Info : Mac OS X 10.13.6 (x86\_64) > JDK Version : Oracle Corporation 1.8.0\_171 [Java HotSpot(TM) 64-Bit Server VM 25.171-b11] > JAVA\_HOME : /Users/AaronZhao/.sdkman/candidates/java/8.0.171-oracle > Random Testing Seed : 8B2518F798FD765C > Project evaluation failed including an error in afterEvaluate {}.

The build runs `$JAVA_HOME/bin/jrunscript` to find information about the the configured java versions the build will use. In your case, it seems it cannot find the javascript implementation: `script engine for language js can not be found` I'm not sure how this could happen. Have you tried a java installation not using sdkman to see if it works? ---

When I use official Oracle jdks, the shell does not complain about errors, Thank you! I'm not sure if this is a bug of sdkman, but I think I need to warn the developers in the README for a doc PR. ---
