Gradle Eclipse 插件

【问题标题】：Gradle Eclipse PluginGradle Eclipse 插件

【问题描述】：

我是 Gradle 新手，我正在尝试配置它来构建 rosjava。我相信我有一个比较简单的多项目配置。一切都通过 gradle install 构建、测试并安装到我的本地 Maven 存储库。但是，当我尝试使用 Eclipse 插件生成 .project 和 .classpath 文件时，它失败了：

Execution failed for task ':rosjava:eclipseClasspath'.
  > Could not resolve all dependencies for configuration 'detachedConfiguration1'.
  > Module version group:ros.rosjava_core, module:rosjava, version:0.0.0-SNAPSHOT, configuration:detachedConfiguration1 declares a dependency on configuration 'archives' which is not declared in the module descriptor for group:ros.rosjava_core, module:rosjava_bootstrap, version:0.0.0-SNAPSHOT

我不确定如何调试它。项目的基本布局是：

rosjava_core/build.gradle
rosjava_core/rosjava/build.gradle
rosjava_core/rosjava_bootstrap/build.gradle

rosjava 项目依赖于 rosjava_bootstrap，如下所示：

dependencies {
  compile project(':rosjava_bootstrap')
}

rosjava_bootstrap 项目没有依赖关系。

以下是血淋淋的细节：

【问题讨论】：

  • 你能发布运行 gradle 的完整输出吗？你用的是什么版本？你在哪个目录运行它？
  • 我用更多细节更新了问题。
  • 会不会像“运行 gradle”eclipse 而不是“gradle rosjava:eclipse”一样简单？似乎找不到其他模块，可能是因为它不是子目录构建的一部分
  • 对不起，引号放错地方了。应该阅读：运行“gradle eclipse”
  • 没有。在为其他子项目生成一些 eclipse 文件后，以同样的方式失败。

标签： java eclipse gradle


【解决方案1】：

java 插件定义了“存档”配置，因此一种可能性是您将 java 插件应用于每个子模块。也可以在没有插件的情况下定义自己的档案配置。这是我在非 java 子模块中使用的：

task jar(type: Jar, dependsOn: compile) {
    from file("build")
    destinationDir=file("dist")
    archiveName="my-custom-archive.jar"
}

configurations {
    archives
}

artifacts {
    archives jar
}

【讨论】：

  • 谢谢，但我已经在使用 java 插件了。源代码和构建脚本在此处可见：code.google.com/r/damonkohler-rosjava-unstable/source/browse Patches welcome ;)
  • 我尝试在我的 (Windows) 机器上运行它，但使用相同版本的 Gradle，它完成时没有出现错误 pastebin.com/raw.php?i=fx7HdRQA。很抱歉，我无法提供更多帮助。
  • 谢谢。我发现如果我没有先运行 gradle install 它实际上也适用于我。而且，事实证明，如果我清除我的 .m2 缓存，gradle install 会失败。我在 gradle 论坛上发布了一个关于此的问题：forums.gradle.org/gradle/topics/…
【解决方案2】：

按照here 的描述修复我的依赖项后，这个问题就消失了。
