在 MacOS 升级到 Big Sur 后，使用 /usr/libexec/java_home 切换 java 家庭停止工作

Question

I have a simple script to switch between different JDK versions. However, after MacOs upgrade to Big Sur, it stop working. Not sure if it's related to OS upgrade or not.

The script setjavahome.sh :

export JAVA_HOME=`/usr/libexec/java_home -v $1`
export PATH=$JAVA_HOME/bin:$PATH

Usually, I call . setjavahome.sh 1.8 . setjavahome.sh 1.8

It will switch java home. But now it doesn't do anything.

If I use /usr/libexec/java_home -V , it's still able to list all the versions.

Just /usr/libexec/java_home -v stop working.

Not sure why it suddently stop working.

Not really an answer to this question, but at least here's a workaround:

PROGRAM="{ if (\$1 ~ \"^$1.*\") print \$NF }"
export JAVA_HOME=`/usr/libexec/java_home -V 2>&1 | awk "$PROGRAM"`
