设置JAVA_HOME为在Gradle JVM中的Eclipse中打开JDK11，而不会干扰系统环境变量

Question

I am working in a PoC that would require me to run a Spring Boot project (developed for Java-8) in Compatibility mode pointing JAVA_HOME to Open JDK-11 .

This is perfectly working fine when I build and run the project from the command-prompt where I can set JAVA_HOME manually before executing gradle tasks.

This is perfectly working fine, when I import the project in to my IntelliJ and there i get an option to set JAVA_HOME ..

Now my text task is to prove the same by importing the project in to Eclipse-Oxygen .. Am not sure where exactly i should point eclipse to JAVA_HOME .. It is also looking for JRE_HOME .. But it should take everything from gradlew.bat

Gradle-JVM is automatically picked-up in Eclipse from the gradle-wrapper (gradlew.bat ). In gradlew.bat the JAVA_HOME is taken from the System's Environments . This can be overriden in Intellij where it provides us an option to set an gradle-JVM . I wanted to understand how a similar thing can be done in Eclipse

Help please !

You can configure environment variables in the run config of your project. On the Environment tab, you can extend or replace the default environment.
