JVM space exhausted when building a project through gradle

This means the JVM doesn’t have enough memory to compile the Java files. There’s a couple of steps that can be taken.

1. Run ./gradlew clean, which will remove everything including leftovers from previous builds which are no longer relevant.
2. Run ./gradlew --stop, killing other gradle daemons which may be taking up memory.
3. Allocate more memory. This can be done by adding the following to the gradle.properties file.

org.gradle.jvmargs=-Xms128m -Xmx1024m -XX:+CMSClassUnloadingEnabled
