gradle设置外部类路径

Question

I'd like to share the classpath created by gradle with an external application (VIM) by exporting the classpath to $CLASSPATH. I've tried doing this in the shell via calling gradle and setting the variable but there is a bunch of extra output that makes this cumbersome. I've also looked at shelling commands via the gradle script but this seems to create a new shell instance and therefore doesn't affect env variables of the current shell.

Does anyone have any experience accomplishing this? Thanks for the help!

I think an example would help to clarify:

task classpath {
    classpathcmd = "export CLASSPATH=" + sourceSets.test.runtimeClasspath.asPath
    // Prints too much extra text
    println classpathcmd
    // Executes command in another shell instance so the variable is "lost"
    exec {
        executable = "sh"
        args = classpathcmd
    }
    // Stracktrace because of file not found exception
    exec {
        commandLine classpathcmd
    }
 }

您可以为此编写一个任务并调用它（可能使用--quiet ），也可以使用Gradle工具API（可能来自vim插件）。
