如何通过jar设置主类可执行的vanillagroovy项目？

2.添加源代码

让我们添加一个测试包:

mkdir -p src/test/groovy/org/gr8ex

并且测试.我正在使用gedit src/test/groovy/org/gr8ex/HelloTest.groovy:

package org.gr8ex

class HelloTest extends GroovyTestCase {
    void 'test Hello should return "Hello, World!"' () {
        assert new Hello().world == "Hello, World!"
    }
}

让我们执行测试并检查它是否失败:

gradle test

是的,它失败了:

/tmp/gr8ex/src/test/groovy/org/gr8ex/HelloTest.groovy: 5: unable to resolve class Hello 
 @ line 5, column 12.
          assert new Hello().world == "Hello, World!"
          ^

1 error

:compileTestGroovy FAILED

我们来添加源文件夹

mkdir -p src/main/groovy/org/gr8ex

和一个源文件(我用过gedit src/main/groovy/org/gr8ex/Hello.groovy).注意它已经有我们的static main方法:

package org.gr8ex

class Hello {
    def getWorld() {
        "Hello, World!"
    }

    static main(args) {
        println new Hello().world
    }
}

再次测试(带gradle test)并断言我们得到消息BUILD SUCCESSFUL:

$ gradle test
:compileJava UP-TO-DATE
:compileGroovy
:processResources UP-TO-DATE
:classes
:compileTestJava UP-TO-DATE
:compileTestGroovy
:processTestResources UP-TO-DATE
:testClasses
:test

BUILD SUCCESSFUL
