What I am tried to add parameter in my $HOME/.gradle/gradle.properties:

org.gradle.jvmargs=-Xmx8096m -XX:MaxPermSize=8096m -XX:+HeapDumpOnOutOfMemoryError

But the problem not solved,what should I do to fix?

Answer 1

I add gradle.properties file in my root project dir,and add this config:

org.gradle.jvmargs=-Xmx4096M

works. From the error message we can know the Daemon JVM spcace exhausted. This is the Gradle official docuemnt about this config:

Specifies the JVM arguments used for the Gradle Daemon. The setting is particularly useful for configuring JVM memory settings for build performance. This does not affect the JVM settings for the Gradle client VM. The default is -Xmx512m "-XX:MaxMetaspaceSize=256m".
