[GRADLE-2357] Running gradle with --no-daemon still forks a daemon when org.gradle.jvmargs are specified Created: 15/Jun/12  Updated: 10/Feb/17  Resolved: 10/Feb/17

 Description   

To avoid OOM exceptions we specify the following in our gradle.properties when running the daemon:
org.gradle.jvmargs=-XX:MaxPermSize=256m -Xms256m -Xmx512m

However when we don't want to run the daemon (f.e. because there's a plugin doing System.console stuff which doesn't work in daemon-style) we should specify --no-daemon or put or.gradle.daemon=false in our gradle.properties.

However when doing either of the above settings a daemon is still forked:

Note: in order to honour the org.gradle.jvmargs and/or org.gradle.java.home values specified for this build, it is necessary to fork a new JVM.
This forked JVM is effectively a single-use daemon process. In order to avoid the slowdown associated with this extra process, you might want to consider running Gradle with --daemon.

Basically there's no way to not run gradle as a daemon when there's a org.gradle.jvmargs specified. This is quite annoying.

This bug, combined with GRADLE-2193, is causing us all kinds of headaches..

Comment by Martin Kleppmann [ 26/Jun/14 ]

This forking is a problem for plugins that need to read from stdin, e.g. a password for publishing to a repository or a passphrase for decrypting a signing key. We shouldn't have to put passwords in plaintext files — asking for them interactively is much preferable. Here's an issue: https://github.com/bmuschko/gradle-nexus-plugin/issues/27

An alternative solution would be to attach the parent process' standard input to the forked process (with the daemon, that might be harder). Are there any plans to do that?

Another work around is to not set "org.gradle.jvmargs" and instead set the GRADLE_OPTS env var to include you JVM params ( i.e. -XX:MaxPermSize=256m -Xms256m -Xmx512m )
