Eclipse Gradle 插件无法在全新 Luna 安装时检索 Gradle 发行版

Question

我真的对 Luna 中的 Gradle 和 Groovy 插件感到沮丧。我最初是从 STS 3.6.4 开始的，但我的 Groovy View 中的许多绑定(bind)根本不起作用，而且我没有收到任何关于此问题的帖子的回复。

然后我决定尝试全新的 Eclipse Luna 安装，然后在上面安装 Groovy 和 Gradle 插件。当我最终导入我的 Groovy 项目时，我看到了奇怪的错误:

org.gradle.jvm.tasks.Jar
Could not fetch model of type 'EclipseProject' using Gradle distribution 'https://services.gradle.org/distributions/gradle-2.2.1-bin.zip'.

我知道 Eclipse Mars 将完全取代这个 Gradle 工具，我只希望我能活到那时。

日志中的堆栈跟踪是这样的:

Answer 1

看来我已经设法解决了这个问题，尽管我不确定这里到底发生了什么。

我意识到也许这个“org.gradle.jvm.tasks.Jar”类可能不在它试图下载的 Gradle 版本(2.2.1)中，但是 Gradle 插件或我的构建脚本中的某些东西希望它存在.我确实在我的自定义 Gradle 插件中引用了该任务，所以这可能是导致问题的引用。

我终于进入了 Gradle 首选项，看看它认为它使用的是什么版本的 Gradle，它只说“使用 Gradle Wrapper Default”，不管是什么。我尝试将该属性更改为指向我的 Gradle 2.3 发行版，现在该错误已消失。
