Can't debug intellij plugin - invalid initial heap size

Question

I'm developing an intellij plugin and when i'm trying to run the plugin (or debug it) i keep getting the following error:

Could not create the Java virtual machine. Invalid initial heap size: -Xms128m

The JVM parameters in the Run\\Debug configurations are (by default):

-Xms128m -Xmx512m -XX:MaxPermSize=250m -XX:ReservedCodeCacheSize=64m -XX:+UseCodeCacheFlushing -ea -Dsun.io.useCanonCaches=false

So eventually I can't debug or run my code.

Answer 1

JVM is unhappy because there are newline characters between options. You can confirm this by copy-pasting VM Options into a text editor.

Answer 2

I met the same problem today. I solved this problem by making the checked and select the IDEA Plugin Sdk。My Idea version is 11.1.5. you can try it..
