JAVA_HOME libgdx错误macOS Sierra

Question

I'm trying to generate a libgdx project using "project generator" but it shows this error:

ERROR: JAVA_HOME is set to an invalid directory: /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

But I have installed the JAVA 1.8, using the terminal command it shows this:

$ java -version

java version "1.8.0_101"  
Java(TM) SE Runtime Environment (build 1.8.0_101-b13)    
Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)

So how to setup the right jvm, someone have any suggestion or the solution to correct this issue?

Answer 1

I believe you are using unix type operating system. If so do the following steps :

echo "export JAVA_HOME=`/usr/libexec/java_home`"

If it prints empty like below

JAVA_HOME=

then you should install java first from oracle site : https://www.oracle.com/technetwork/java/javase/downloads/jdk12-downloads-5295953.html

If it prints like this :

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home

Then you should set your Java Home path like following way :

export JAVA_HOME=`/usr/libexec/java_home`

Please check this out. This link might give you lucid view to set Java Home to valid path.

Answer 2

What happens when you type this command in terminal: echo $JAVA_HOME

If that is showing the older version of java, you will just need to update your JAVA_HOME settings.

Set JAVA_HOME using this command in Terminal: export JAVA_HOME= path to JDK

echo $JAVA_HOME on Terminal one more time to confirm the path was changed.

One other thing to keep in mind is sometimes, depending on the programs/projects, you could run into an issue between 32 and 64 bit versions. You might want to doublecheck you are using the right one.
