I’m using Script step to excute these line:

```
java -version

brew tap homebrew/cask-versions
brew cask install java11

/usr/libexec/java_home -V

cd /Library/Java/JavaVirtualMachines/
ls
export JAVA_HOME=$(/usr/libexec/java_home -v 11)
echo $JAVA_HOME

java -version

```

But it can not change the version. Here is the log:

```

Just wanted to update here with good news! The stacks now have both openjdk 8 and openjdk 11 installed. By default, openjdk 8 will be active. To change to use openjdk 11, you just need a simple script step. Instructions and what needs to be in the script - - all documented in our devcenter!
