The build failed when running the command about swiftjava

[johnno1962]

Johns-MacBook-Air:swift johnholdsworth$ find $JAVA_HOME -name libjvm.*
/Library/Java/JavaVirtualMachines/jdk1.8.0_101.jdk/Contents/Home/jre/lib/server/libjvm.dylib
Johns-MacBook-Air:swift johnholdsworth$

export JVM_LIBRARY_PATH=/Library/Java/JavaVirtualMachines/jdk1.8.0_101.jdk/Contents/Home/jre/lib/server

@johnno1962 thanks for you reply. i tried your command but did not work. can you explain a bit what is this doing?

what is johnholdsworth$ suppose to be? I guess it should be replaced by something else, isn't it? Look forward to hear from you again.

[johnno1962]

You need to find your JAVA_HOME where you Java installation is it will be something like:

echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.8.0_101.jdk/Contents/Home

then setup a new variable for the JVM_LIBRARY_PATH
export JVM_LIBRARY_PATH=$JAVA_HOME/jre/lib/server

then the command should work.

On Macos The best way to find Java home is:
export JAVA_HOME=/usr/libexec/java_home --version 1.8

Then you can reference the env variable in your build

How silly I was. now it works after I set the JAVA_HOME correctly. thanks guys!

@gagaJay java 1.8 needed right? it doesn't work on 1.6 as JAVA_HOME? (Solved)

apple$ /usr/libexec/java_home -V
