Import SpringSource into IDEA.But had a error "Unrecognized VM option 'MaxMetaspaceSize=1024m'"

Question

I want to import Spring-framework into IDEA. I followed the document, and run the following command, but I had a error:

spring-framework>gradlew.bat :spring-oxm:compileTestJava cleanIdea idea

Unrecognized VM option 'MaxMetaspaceSize=1024m'
Could not create the Java virtual machine.

What's wrong?

My OS is Win7. JDK version is as following :

>java -version
java version "1.6.0_38"
Java(TM) SE Runtime Environment (build 1.6.0_38-b05)
Java HotSpot(TM) Client VM (build 20.13-b02, mixed mode, sharing)

>javac -version
javac 1.6.0_38

Answer 1

As @VMN said, MaxMetaspaceSize is supported in Java 8 and have bugs.

You can try one of this:

1)Download JDK8 and set it to you environment.

2)Edit gradlew.bat(windows) or gradlew(linux), remove the VM option MaxMetaspaceSize.

In case you are configuring WildFly, remove option from installation file. – Homophonous

Answer 2

I had the same error. Cause of error is in Java 8 option "MaxMetaspaceSize=1024m", that not supported in early versions. Spring developers use this option in master branch. After switching to the 3.2.x branch project was successfully imported.

You have three choice to slove this problem

1)use JDK8 as your enviroment;

2)ignore or delete "set GRADLE_OPTS=-XX:MaxMetaspaceSize=1024m -Xmx1024m -XX:MaxHeapSize=256m %GRADLE_OPTS%" in gradle.bat;

3)choose another branch like 3.2.x
