考虑到 Java 1.9 现在已经发布了一段时间，我仍然对使用 eclipse 和 buildship 启动和运行 1.9 项目有多么困难感到惊讶。

我现在花了 2 天时间试图让这架飞机飞起来，而且走了很远，但一个问题是我只是没有起步：

最重要的是 build.gradle 文件中的整个“eclipse.classpath.file.whenMerged”内容（我的文件见下文）。

因此，我的问题有两个：

  1. 我是否错过了一些让 Gradle 和 buildship 的拼图支持更容易的东西？
  2. 我该怎么做才能不手动修补命令行（如上面的链接中所述）？

由于我目前正在为我的团队评估 Eclipse/Gradle/Buildship 的支持，我需要解决第二个问题。否则我团队中的开发人员会发疯的。因此，我也在考虑离开 Eclipse。

附带问题：其他 IDE 对模块和 Gradle 的支持有多好？

我在用

  • Eclipse 2020-12 (4.18.0.v20201202-1800)
  • Gradle 3.1.4.v20200326-1743 的 Eclipse 插件
  • 爪哇 12
  • 6.7.1 年级

谢谢
