使用 Gradle 构建具有依赖项的 jar [英] Using Gradle to build a jar with dependencies

问题描述

我有一个多项目构建，我在其中一个子项目中放置了一个构建胖 jar 的任务.我创建的任务类似于在食谱中描述的任务.>

I have a multiproject build and I put a task to build a fat jar in one of the subprojects. I created the task similar to the one described in the cookbook.

jar {
  from configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
  manifest { attributes 'Main-Class': 'com.benmccann.gradle.test.WebServer' }
}

运行它会导致以下错误:

Running it results in the following error:

原因:您无法更改不在的配置未解决的状态！

Cause: You can't change a configuration which is not in unresolved state!

我不确定这个错误是什么意思.我也在 Gradle JIRA 上报告了这个，以防它是一个错误.

I'm not sure what this error means. I also reported this on the Gradle JIRA in case it is a bug.

推荐答案

我发布了一个解决方案 在针对 Gradle 的 JIRA 中:

I posted a solution in JIRA against Gradle:

// Include dependent libraries in archive.
mainClassName = "com.company.application.Main"

jar {
  manifest { 
    attributes "Main-Class": "$mainClassName"
  }  

  from {
    configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
  }
}

注意 mainClassName 必须出现在 jar { 之前.

Note that mainClassName must appear BEFORE jar {.
