Question

使用以下gradle.build文件在IntelliJ中使用Gradle构建时：

version '1.0-SNAPSHOT'
apply plugin: 'java'
apply plugin: 'idea'

sourceCompatibility = 1.8
repositories {
    mavenCentral()
}

dependencies {

    // https://mvnrepository.com/artifact/org.jdom/jdom
    compile (
            [group: 'org.jdom', name: 'jdom', version: '2.0.0'],
            [group: 'org.controlsfx', name: 'controlsfx', version: '8.40.14'],
            [group: 'net.java.openjfx.backport', name: 'openjfx-78-backport-compat', version: '1.8.0.1']
    )
    testCompile group: 'junit', name: 'junit', version: '4.12'
}

jar {
    manifest {
        from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
        attributes 'Main-Class': 'de.to.main.class.itv.Main'
    }
}

我收到以下错误：

9:44:43 PM: Executing task 'build'...

我猜测路径中会出现whitspace错误，但是在将服务目录路径更改为没有whitspace的路径之后，错误将保持不变。

目标是构建一个包含外部依赖项的项目jar。问题是，提供的注释有什么问题？

Answer 1

我认为你在这里遇到了方法范围问题。

在你的街区：

jar {
  manifest {
    from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
    attributes 'Main-Class': 'de.to.main.class.itv.Main'
  }
}

您首先在jar任务中调用manifest(Action<? super Manifest> configureAction)方法。在该机构内部，您正在Manifest类型上调用from(Object... mergePath)。

指定要合并到此清单中的其他清单。

from上的方法名称Manifest会影响来自AbstractCopyTask（Jar继承自）的各种from方法。

如果要使用工件配置事物包，您应该做的是在任务类型上调用from。只需将from移到manifest之外，您就会看到更明确的信息，或者事情会有效。

jar {
  from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } }
  manifest {
    attributes 'Main-Class': 'de.to.main.class.itv.Main'
  }
}
