Adding classpath entries using Gradle's Application plugin

Question

I\'m using Gradle\'s Application plugin to generate the install for a standalone java application. I have a configuration file I need to put on the classpath but I can\'t seem t

Answer 1

I did a variant of Martin Dow's recipe below:

I replace 'APP_HOME=' with 'export APP_HOME=' in the start script.

Then my code can do System.env.get("APP_HOME") and then navigate to e.g. the conf/ folder.

This is my Gradle hack:

tasks.startScripts {
  doLast {
    def scriptFile = file "${outputDir}/${applicationName}"
    scriptFile.text = scriptFile.text.replaceAll('APP_HOME=',  'export APP_HOME=')
  }
}

Example of Java code in the app:

String APP_HOME = System.env().get("APP_HOME");
Properties p = new Properties();
p.load(new FileInputStream(APP_HOME + "/conf/myapp.properties"))

Hope this helps.

NOTE: "export" does not work in Windows!
