Import SpringSource into IDEA. But there was an error "Unrecognized VM option" MaxMetaspaceSize = 1024m "

I want to import Spring-framework into IDEA. I followed the document and executed the following command, but I had an 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. The JDK version is as follows:

 >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

As @VMN said, MaxMetaspaceSize is supported in Java 8 and has errors .

You can try the following:

1) Download JDK8 and install it in the environment.

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

I had the same error. The cause of the error is in the Java 8 option "MaxMetaspaceSize = 1024 m", which is not supported in earlier versions. Spring developers use this option in the main branch. After the transition to the project, branches 3.2.x were successfully imported.

You have three options for solving this problem.

1) use JDK8 as your environment;

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

3) select another branch, for example 3.2.x
