Question

这应该是最简单的问题，但我在从Gradle测试任务访问System变量时遇到问题。 what I am doing中必定存在拼写错误，因为我确信这种语法是正确的，但它不起作用。我希望有人可以帮我识别下面这段代码的问题吗？

// my gradle build says the following line is a deprecated method    
//systemProperties = System.getProperties()

// this line always returns 1 on a multiprocessor system
println 'NUMBER_OF_PROCESSORS is ' +
     System.getProperty( "NUMBER_OF_PROCESSORS", "1" )

// this line also always returns the default for TMP var
println 'TMP is ' + System.getProperty( "TMP", "C:\\Temp" )

注意：我也问the question here但是由于它是一个封闭的线程，我不确定我是否会在那里得到答案。另外，我有read the doc彻底，但没有帮助。

我尝试了这些，但也失败了：

test {
    println ""
    ENV = System.getProperties()
    println "TMP is " + ENV['TMP']
    println ""
}

task testa(Type:Test) { 
    println ""
    println "HOMEPATH = " + System.getProperty( "HOMEPATH", "defaultpath" )
    println "TMP = " + System.getProperty( "TMP", "defaulttmp" )
    println ""
}

task testb(Type:Test) {
    println ""
    println "HOMEPATH = " + System.properties['HOMEPATH']
    println "TMP = " + System.properties['TMP']
    println ""
}

task testc(Type:Test) {
    // pass a arg to this test like -PMYARG=anything
    println ""
    println "Parg = " + System.properties['MYARG']
    println ""
}

testWorks {
    println ""
    ENV['ok'] = "good to go"
    println "this test is " + ENV['ok']
    println ""
}

要使Gradle JVM的系统属性可用于测试，您可以执行以下操作：

test {
    systemProperties = System.properties
}

或者，如果您已宣布其他Test任务：

tasks.withType(Test) {
    systemProperties = System.properties
}

在Gradle构建脚本中使用系统属性
