Question

好吧，我现在已经把头撞到了墙上很长一段时间了，现在我甚至不知道要搜索什么来寻找解决方案，这里是我的文件

的build.gradle

    //Applying the Gradle BND Plugin for Workspace Builds
    //https://github.com/bndtools/bnd/blob/master/biz.aQute.bnd.gradle/README.md
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "biz.aQute.bnd:biz.aQute.bnd.gradle:${bnd_version}"
    }
}

apply plugin: 'biz.aQute.bnd.workspace'
apply plugin: 'java'

    // Repositorios, aguante Maven Central.
repositories {
    mavenCentral()

    /* Excluded, uso la dependecia de otro lado ahora.
    flatDir {
        dirs '/home/feddericokz/devTools/Equinox/Equinox-Oxygen-1a/plugins'
    }
    */
}

    // Dependencias
dependencies {
    // https://mvnrepository.com/artifact/org.osgi/org.osgi.core
    compile group: 'org.osgi', name: 'org.osgi.core', version: '6.0.0'
}

*/

rootProject.name = 'bndWorkspace'

include 'com.feddericokz.helloworld'

当尝试从命令行运行gradle jar时，我收到错误，因为编译器无法找到osgi依赖项来编译类

我做错了什么？

Answer 1

如果您正在使用Bnd工作区模型构建，那么必须使用bnd.bnd Bnd指令配置每个项目的-buildpath文件的构建路径。然后Bnd gradle插件将使用该信息来编写java编译的配置。

您的示例显示为根gradle项目设置编译依赖项是错误的，因为（1）您应该在项目的-buildpath文件中使用bnd.bnd并且（2）它是在根项目中完成，这对于com.feddericokz.helloworld项目等任何子项目都没有意义。

因此，请将build.gradle文件更改为不应用＆＃39; java＆＃39;插件到根项目，而不是为根项目设置编译依赖项并更改Bnd工作区，以便工作区（cnf）配置存储库以访问所需的包，例如https://github.com/osgi/enroute.workspace/blob/4070ff6668a1ee79b9b01cfa4caab86869247e7b/cnf/ext/enroute.bnd#L22-L28，然后设置每个项目的bnd.bnd文件都在-buildpath上包含所需的捆绑包。

目前还不清楚此行中是否定义了bnd_version：

classpath "biz.aQute.bnd:biz.aQute.bnd.gradle:${bnd_version}"

考虑添加gradle.properties文件：

bnd_version=3.5.0

（或任何适用的版本）。尽管我可以重现你的情况，但我的例子对我有用。

Gradle compileJava任务一直失败
