How to set Gradle environment variables?

问题

I'm trying to execute a Gradle command-line task -setupDecompWorkspace to set up Minecraft Forge, but the task gets stuck on decompileMC. I've tried the first solution from this issue, but it didn't work. The second solution suggest setting the GRADLE_OPTS environment variable to -Xmx2G. I don't exactly know how to do this. After searching online for a couple of hours I am still found with no answer. Even the official Gradle documentation doesn't help. Do I need to declare the variable in the gradle.properties file, enter it as a command-line argument or something completely different?

回答1:

-Xmx2G is a JVM command line parameter, if you want to set it as a Gradle property just add it to the gradle.properties file in your project root:

org.gradle.jvmargs=-Xmx2G
