java - GradlecompileJava任务不断失败

Question

好吧，我已经用头撞墙很长一段时间了，现在我什至不知道要搜索什么来找到解决方案，这是我的文件

构建.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'
}

设置.gradle

/*
 * This settings file was generated by the Gradle 'init' task.

 * The settings file is used to specify which projects to include in your build.
 * In a single project build this file can be empty or even removed.
 *
 * Detailed information about configuring a multi-project build in Gradle can be found

 */

/*
// To declare projects as part of a multi-project build use the 'include' method
include 'shared'
include 'api'
include 'services:webservice'
*/

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？

编辑:拼写错误

如果您使用 Bnd 工作区模型构建，那么您必须通过每个项目的 bnd.bnd 配置构建路径。使用 -buildpath 文件并指令。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，这是错误的，因为 (1) 您应该使用 -buildpath在项目的bnd.bnd文件和(2)它是在根项目中完成的，这对于像您的 com.feddericokz.helloworld 这样的任何子项目都没有意义。项目。

因此，更改您的 build.gradle 文件，不要将“java”插件应用到根项目，并且不为根项目设置编译依赖项，并更改您的 Bnd 工作区，以便工作区 ( cnf ) 已配置要访问的存储库所需的 bundle ，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文件以在 -buildpath 上拥有所需的 bundle .
