分级compileJava任务不断失败

Question

好吧，我已经用头撞墙了好长一段时间了，现在我甚至不知道该找什么来找到解决方案了，这是我的文件

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'
}

settings.gradle

/*

include 'shared'
include 'api'
include 'services:webservice'
*/

rootProject.name = 'bndWorkspace'

include 'com.feddericokz.helloworld'

当试图从命令行运行gradle jar时，我得到一个错误，因为编译器找不到编译类的osgi依赖项。

我做错什么了？

编辑:一个错误

Answer 1

如果使用Bnd工作区模型构建，则必须使用bnd.bnd Bnd指令通过每个项目的-buildpath文件配置构建路径。然后，Bnd插件将使用这些信息为java编译编写配置程序。

您的示例显示了为根级项目设置编译依赖关系，这是错误的，因为(1)您应该在项目的-buildpath文件中使用bnd.bnd，(2)它是在根项目中完成的，这对您的com.feddericokz.helloworld项目这样的任何子项目都没有意义。

因此，将build.gradle文件更改为不将'java‘插件应用于根项目，而不设置根项目的编译依赖项，并更改Bnd工作区，以便工作区(cnf)已经配置了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 )，然后将每个项目的bnd.bnd文件设置为在-buildpath上具有所需的捆绑包。

尚不清楚是否在这一行中定义了bnd_version：

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

考虑使用以下内容添加一个gradle.properties文件：

bnd_version=3.5.0

(或按任何版本分摊)。尽我所能再现你的情况，我的例子适用于我。
