Can't debug intellij plugin - invalid initial heap size

votes

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.

Have you tried setting -Xms to a higher value? - weltraumpirat
@weltraumpirat yes, tried to increas\decrease the value - axelrod
Usually this is because you've made a typo in the options. Hard to tell from your pasted options. I'd try to remove all if them and entering/addung them one at the time again and make sure there's no spaces or things like that in the wrong places. - Peter Svensson

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