如何使用GroovyShell传递JVM参数和脚本参数?

How to pass JVM arguments and script argument using GroovyShell?

问题

以下是翻译好的内容:

所以我有一个Groovy脚本:

// TestScript.groovy
println args

然后在一个Gradle任务中我有:

test {
    String profile = System.getenv("spring.profiles.active")
    jvmArgs '-Dspring.profiles.active=$profile' // 这个不起作用! :(
    
    doLast {
        new GroovyShell().run(file('package.TestScript.groovy'))
    }
}

我需要做两件事情:

a) 将程序参数传递给TestScript.groovy,以便它将打印出args数组。

b) 将Spring Boot配置文件传递给JVM,即 spring.profiles.active=dev

有什么建议吗?

注意,我正在使用Groovy 2.4.3,并参考了这个文档:http://docs.groovy-lang.org/2.4.3/html/api/groovy/lang/GroovyShell.html

我尝试了以下不成功的方法:

doLast {
    Binding b = new Binding();
    b.setVariable('spring.profiles.active', $profile)
    new GroovyShell(b).run(file('package.TestScript.groovy'))
}
英文:

So I have a Groovy script:

// TestScript.groovy
println args

Then in a Gradle task I have

test {
  String profile = System.getenv("spring.profiles.active")
  jvmArgs '-Dspring.profiles.active=$profile" // THIS DOES NOT WORK! :(

  doLast {
    new GroovyShell().run(file('package.TestScript.groovy'))
  }
}

What I need to do is two things:

a) Pass into TestScript.groovy program arguments so it will print out the args array

b) Pass to JVM the Spring Boot profile i.e. spring.profiles.active=dev

Any suggestions?

Note, I'm using Groovy 2.4.3 and referring to this documentation: http://docs.groovy-lang.org/2.4.3/html/api/groovy/lang/GroovyShell.html

I tried the following which was unsuccessful:

doLast {
  Binding b = new Binding();
  b.setVariable('spring.profiles.active', $profile)
  new GroovyShell(b).run(file('package.TestScript.groovy'))
}

在这里查看工作示例...

如果我们有一个将参数写入文件的脚本:

// TestScript.groovy

try {
    new File("out.txt").withWriter { writer ->
        args.each { arg ->
            writer.write("TRACER arg : ${arg}\n")
        }
    }
} catch (Exception ex) {
    new File("error.txt").withWriter { writer ->
        writer.write("TRACER caught exception ${ex.message}\n")
    }
}

然后我们可以使用以下 Gradle 任务进行测试:

test {
    doLast {
        def profile = project["spring.profiles.active"]

        def script = new File("${projectDir}/TestScript.groovy")
        def args = ["exampleArgVal1", "exampleArgVal2", profile]

        new GroovyShell().run(script, args)
    }
}

请注意,参数是通过以下方式传递给 Gradle 的:

gradle clean test -Pspring.profiles.active=TEST_PROFILE
英文:

Working example here ...

If we have a script that writes arguments to a file:

// TestScript.groovy

try {
    new File("out.txt").withWriter { writer ->
        args.each { arg ->
            writer.write("TRACER arg : ${arg}\n")
        }
    }
} catch (Exception ex) {
    new File("error.txt").withWriter { writer ->
        writer.write("TRACER caught exception ${ex.message}\n")
    }
}

then we can test it with this Gradle task:

test {
    doLast {
        def profile = project["spring.profiles.active"]

        def script = new File("${projectDir}/TestScript.groovy")
        def args = ["exampleArgVal1", "exampleArgVal2", profile]

        new GroovyShell().run(script, args)
    }
}

Note that parameters are passed to Gradle like so:

gradle clean test -Pspring.profiles.active=TEST_PROFILE
