使用gradle“run”任务运行main方法

我想通过gradle任务运行我的main方法

这是我通过cmd运行的方式：

java -cp RTMonitor.jar com.bla.MainRunner first_arg

应该如何用gradle写？

 run { args += ['java -cp RTMonitor.jar com.bla.MainRunner first_arg'] } 

更新

我努力了

 task myRun(type: JavaExec) { classpath configurations.main main = "com.bla.runners.StatsLogGenerator" args "arg1", "arg2" } 

我得到了：

Error:(71, 0) Could not find property 'main' on configuration container.

 the I have tried: task myRun(type: JavaExec) { classpath "configurations.main" main = "com.bla.runners.StatsLogGenerator" args "arg1", "arg2" } 

我收到一个错误：

 FAILURE: Build failed with an exception. 17:49:21.855 [ERROR] [org.gradle.BuildExceptionReporter] 17:49:21.856 [ERROR] [org.gradle.BuildExceptionReporter] * What went wrong: 17:49:21.856 [ERROR] [org.gradle.BuildExceptionReporter] Execution failed for task ':myRun'. 17:49:21.856 [ERROR] [org.gradle.BuildExceptionReporter] > Process 'command '/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home/bin/java'' finished with non-zero exit value 1 17:49:21.864 [ERROR] [org.gradle.BuildExceptionReporter] 17:49:21.865 [ERROR] [org.gradle.BuildExceptionReporter] * Exception is: 17:49:21.866 [ERROR] [org.gradle.BuildExceptionReporter] org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':myRun'. 17:49:21.867 [ERROR] [org.gradle.BuildExceptionReporter] at org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter.executeActions(ExecuteActionsTaskExecuter.java:69) 17:49:21.882 [ERROR] [org.gradle.BuildExceptionReporter] at org.gradle.process.internal.DefaultExecHandle$ExecResultImpl.assertNormalExitValue(DefaultExecHandle.java:361) 17:49:21.882 [ERROR] [org.gradle.BuildExceptionReporter] at org.gradle.process.internal.DefaultJavaExecAction.execute(DefaultJavaExecAction.java:31) 

但是当我通过Intellij运行时，每个thig工作正常

最简单的可能就是使用应用程序插件。 将apply plugin: 'application'添加到build.gradle并设置mainClassName = com.bla.MainRunner 。 要向主类添加参数，请修改运行任务并编辑args属性

 run { args += 'first_arg' } 

Classpath是从主sourceSet自动获取的，如果你想要不同的，你可以编辑run task的classpath属性。

如果需要更多自定义，可以像这样定义自己的JavaExec类型的任务

 task myRun(type: JavaExec) { classpath sourceSets.main.runtimeClasspath main = "com.bla.MainRunner" args "arg1", "arg2" }
