How to disable Gradle daemon in IntelliJ Idea?

Question

I need to disable the Gradle daemon in IntelliJ Idea, because somehow Scala plugin is not working with the daemon (the compilation fails with NullPointerException). I have tried to edit my IntelliJ Gradle build configurations to include a JVM system parameter -Dorg.gradle.daemon=false:

Also I've tried to use --no-daemon flag at the same place (Script parameters and VM options). Also I've tried to specify these options in the Preferences -> Gradle menu of IntelliJ. None of these attempts gave any result, the daemon continue to start, so I have to kill it before running/compiling for the second time.

Neither disabling daemon explicit in ~/.gradle/gradle.properties according to https://docs.gradle.org/current/userguide/gradle_daemon.html#N10473 doesn't have any effect.

How can I disable the Gradle daemon usage in IntelliJ Idea?

Answer 1

IntelliJ interacts with Gradle via the Gradle tooling API, which always uses the daemon. i.e. There is no way to turn it off.

What you could do (after filing a bug report) is not to use the IntelliJ Gradle integration but instead generate IntelliJ project files with

gradle idea

Answer 2

I had a related problem and managed to disable the daemon through a config - I added org.gradle.daemon=false to a gradle.properties file in the project root folder. As explained here: Disabling Gradle daemon in a specific project.

Answer 3

To disable the daemon for a single command (or a single IntelliJ run configuration), you can also pass org.gradle.daemon=false as a VM Option:

-Dorg.gradle.daemon=false

Answer 4

Because of lack of support of old libraries I moved a project from gradle to maven build management tool. But Intellij always wanted me to trigger a gradle changes import: additionally to "Maven project needs to be updated", there was also a "Gradle project needs to be updated" when I did changes to i.e. dependencies in pom.xml, with no integration of gradle in the project source files at all, no wrapper etc.

In my case I was able to get rid of Intellij bothering me with gradle by deleting the line <property name="settings.editor.selected.configurable" value="reference.settingsdialog.project.gradle" /> in .idea/workspace.xml and deleting the file .idea/gradle.xml in Intellij IDEA Ultimate 2019.2.
