Too small initial heap error - stanford parser

I am trying my hands on the Stanford dependency parser. I tried running the parser from command line on windows to extract the dependencies using this command:

java -mx100m -cp "stanford-parser.jar" edu.stanford.nlp.trees.EnglishGrammaticalStructure -sentFile english-onesent.txt -collapsedTree -CCprocessed -parserFile englishPCFG.ser.gz

I am getting the following error:

Error occurred during initialization of VM
Too small initial heap

I changed the memory size to -mx1024, -mx2048 as well as -mx4096. It didn't change anything and the error persists.

What am I missing?

Type -Xmx1024m instead of -mx1024.

See

It should be -mx1024m. I skipped m.

One more thing: in the -cp, the model jar should also be included.

... -cp "stanford-parser.jar;stanford-parser-3.5.2-models.jar"...

(assuming you are using the latest version).

Otherwise an IO Exception will be thrown.

There may be some arguments that are preexisting in the IDE. In eclipse: Go to-> Run as-> run configuration-> Arguments then Delete the arguments that are used previously. Restart your eclipse. Worked for me!
