Is There An Option For dynamic.classpath?

My classpath got too long on Windows and I couldn't launch from IDEA.
Setting this option in the workspace.xml fixed it

<component name="PropertiesComponent">
  <property name="dynamic.classpath" value="true" />

Can this be set at the Project level or the system level via the GUI?

IDE should detect long classpath and suggest to enable this option automatically, see my answer here for details: .

If it was not suggested, please file a bug at and specify what run/debug configuration and compiler you are using.

Hi, I currently IntelliJ version 2018.3, I did the change, but still unable to run my JUnit tests.

I still have the message Command line is too long.

I change the value of Shorten command line:

  • JAR manifest don't work for me.
  • java Wrapper class works but couldn't load correctly quasar library.


thank you for your help.
