Gradle-没有主清单属性 [英] Gradle - no main manifest attribute

问题描述

我正在用Gradle构建一个JAR文件.当我尝试运行它时，我得到了错误

I'm building a JAR file with Gradle. When I try to run it I get the error

在RxJavaDemo.jar中没有主清单属性

no main manifest attribute, in RxJavaDemo.jar

我尝试操纵Manifest属性，但我想我忘记在其中添加依赖项或其他内容.我到底在做错什么?

I tried manipulating the Manifest property but I think I'm forgetting to add the dependencies or something to it. What exactly am I doing wrong?

apply plugin: 'java'
apply plugin: 'application'

mainClassName = 'demo.MainDashboard'

dependencies {
    compile files ("H:/Processes/Development/libraries/hikari-cp/HikariCP-2.4.1.jar")
    compile files ("H:/Processes/Development/libraries/controls-fx/controlsfx.jar")
    compile files ("H:/Processes/Development/libraries/database_connections/sqlite-jdbc-3.8.6.jar")
    compile files ("H:/Processes/Development/libraries/guava/guava-18.0.jar")
    compile files ("H:/Processes/Development/libraries/rxjava/rxjava-1.0.12.jar")
    compile files ("H:/Processes/Development/libraries/rxjava-extras/rxjava-extras-0.5.15.jar")
    compile files ("H:/Processes/Development/libraries/rxjavafx/RxJavaFX-1.0.0-RC1-SNAPSHOT.jar")
    compile files ("H:/Processes/Development/libraries/rxjavaguava/rxjava-guava-1.0.3.jar")
    compile files ("H:/Processes/Development/libraries/rxjava-jdbc/rxjava-jdbc-0.6.3.jar")
    compile files ("H:/Processes/Development/libraries/slf4j/slf4j-api-1.7.12.jar")
    compile files ("H:/Processes/Development/libraries/tom-commons/tom-commons.jar")
}

sourceSets {
    main.java.srcDir "src/main/java"
    main.resources.srcDir "src/main/resources"
}

jar { 
    manifest {
    attributes(
        "Class-Path": configurations.compile.collect { it.getName() }.join(' '))
    }
    from configurations.compile.collect { entry -> zipTree(entry) }
}

推荐答案

尝试更改清单属性，例如:

Try to change your manifest attributes like:

jar {
  manifest {
    attributes(
      'Class-Path': configurations.compile.collect { it.getName() }.join(' '),
      'Main-Class': 'hello.HelloWorld'
    )
  }
}

，然后将'hello.helloWorld'更改为'<your packagename>.<the name of your Main class>'(您的Main类具有main方法).在这种情况下，您可以在清单中创建一个指向该类的属性，然后运行一个jar.

And then just change 'hello.helloWorld' to '<your packagename>.<the name of your Main class>' (where your Main class has a main method). In this case, you make in your manifest an attribute, which point to this class, then a jar is running.
