Gradle Eclipse Plugin

Question

我是Gradle的新手，我试图将其配置为构建rosjava。我相信我有一个相对简单的多项目配置。一切都通过Gradle安装来构建，测试并安装到我的本地Maven仓库。然而，当我试图使用Eclipse插件生成的.project和classpath文件，它失败：

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 

我不完全知道如何调试这一点。该项目的基本布局是：

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

的rosjava项目取决于rosjava_bootstrap像这样：

dependencies { 
    compile project(':rosjava_bootstrap') 
} 

的rosjava_bootstrap项目没有依赖性。

这里是血淋淋的细节：

Answer 1

固定我的依赖关系描述here后，这个问题就走了。

Answer 2

Java插件定义“档案”配置，所以有一种可能性是你将java插件应用到每个子模块。也可以在不使用插件的情况下定义自己的档案配置。以下是我在我的非Java子模块使用：

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

configurations { 
    archives 
} 

artifacts { 
    archives jar 
}
