How to launch an external process with a plugin jar?

It's possible to pack your executable into zip with your jar. And when installed they will be near each other.

Here is a working example with gradle: https://github.com/Camelcade/Perl5-IDEA/blob/master/build.gradle#L120

I tried to put the executable file manually near the plugin jar and install the plugin package in OS X (Pycharm) .

But  it turns out  not able to find the executable file by the  plugin jar .

I print the user dir as :

System.getProperty("user.dir")  ,

it returns :

/Applications/PyCharm CE.app/Contents/bin

while the installed plugin location is : 

~/Library/Application Support/PyCharmCE2018.2 /xxxxx_plugin

So I try to get the jar path as:

String jarPath = this.getClass().getProtectionDomain().getCodeSource().getLocation().getPath().

but failed with a nullpointerexception.

Is there a way to get the plugin jar path in the code ? 

You can use com.intellij.openapi.application.PathManager.getJarPathForClass to get path to the containing JAR file.

Thanks ,  I just found this API   com.intellij.openapi.application.PathManager and everything works fine.

Just one trick,  all files in the installed plugin directory is set to  -rw-r--r--  , so I have to do chmod +x operation in  code.
