Question

我有一个依赖于Sigar库的Gradle项目，该库使用本机库（作为其传递依赖项）。这是依赖树的相关片段：

+--- sigar:sigar:2.0
|    +--- libsigar-amd64-linux:libsigar-amd64-linux:1.0
|    +--- libsigar-ia64-linux:libsigar-ia64-linux:1.0
|    +--- libsigar-x86-linux:libsigar-x86-linux:1.0
|    +--- sigar-amd64-winnt:sigar-amd64-winnt:1.0
|    \--- sigar-x86-winnt:sigar-x86-winnt:1.0

不幸的是，Gradle似乎没有意识到这些是本机库，并将它们添加到eclipse类路径中，就像它们是常规的jar一样。这会导致Eclipse出错：

我该如何解决这个问题？

修改

我试图从eclipse类路径中排除本机依赖项，如下所示：

configurations {
    natives
    compile.extendsFrom(natives)
}

eclipse {
    classpath {
        minusConfigurations += configurations.natives
        ...
    }
}

dependencies {
    ...

    compile("sigar:sigar:2.0")
    natives("libsigar-amd64-linux:libsigar-amd64-linux:1.0")
    natives("libsigar-ia64-linux:libsigar-ia64-linux:1.0")
    natives("libsigar-x86-linux:libsigar-x86-linux:1.0")
    natives("sigar-amd64-winnt:sigar-amd64-winnt:1.0")
    natives("sigar-x86-winnt:sigar-x86-winnt:1.0")

    ...
}

这只能部分起作用。 Gradle不再将dll和so文件添加到Eclipse类路径中，但仍会添加lib个文件：

Archive for required library: '/home/ghik/.gradle/caches/artifacts-23/filestore/sigar-x86-winnt/sigar-x86-winnt/1.0/lib/1a608efcfd2e8358862b7dce02892fa98d63c97b/sigar-x86-winnt-1.0.lib' in project 'myproject' cannot be read or is not a valid ZIP file

我对Gradle生成的Eclipse构建路径有同样的问题但是我必须通过以下方式调整（部分... lib文件不被尊重？）解决方案：

较新的Groovy版本需要从minusConfigurations += configurations.natives到minusConfigurations += [configurations.natives]
我有一个普通目录，其中安装了库而不是存储库。我可以在native files部分内使用natives代替dependencies（仅在存储库中搜索）

build.gradle摘录了这两个变化：

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

...

configurations{
    natives
    compile.extendsFrom(natives)
  }

sourceSets.main.compileClasspath += [configurations.provided]
eclipse {
    classpath {
      minusConfigurations += [configurations.natives]
    }
  }

dependencies {
    native files('D:/lib/nativeDLL.dll')
}

Answer 2

I had a similar problem with eclipse and gradle 4.3. I finally found a solution, thought I share it with you all:

eclipse {
    classpath {
       file {
            whenMerged { classpath ->
                java.util.List wanted = new java.util.ArrayList()
                def entries = classpath.getEntries()
                entries.each {
                    if (it.path.endsWith('.so')) {
                        println('Removing native library: ' + it.path + ' from eclipse classpath (unreadable to eclipse)')
                    } else {
                        wanted.add(it)
                    }
                }
                classpath.setEntries(wanted)
             }
        }
    }
}
