playframework - 不是有效的 key : eclipse (similar: deliver, 许可证，干净)

Question

我已经下载了类型安全激活器并遵循了以下步骤

activator new HelloWorld play-java
cd HelloWorld
activator build
activator eclipse

我有一个错误

[warn] The global sbt directory is now versioned and is located at /Users/abhi/.sbt/0.13.
[warn]   You are seeing this warning because there is global configuration in /Users/abhi/.sbt but not in /Users/abhi/.sbt/0.13.

我用谷歌搜索这个问题，发现

How to use sbt-eclipse to create Eclipse project files of a project?

Installing sbteclipse

我无法弄清楚这些线程中的答案。我确实创建了一个目录

cd ~/.sbt
mkdir plugins
touch plugins.sbt

但我仍然收到这个错误。有没有人有一个有效的“简洁”解决方案？

Answer 1

在最新的 Play 版本中，默认情况下不包含 sbteclipse 插件。这就是为什么激活器不理解“eclipse”命令的原因。

转到您已经创建的项目文件夹并将以下行附加到 project/plugins.sbt:

addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "4.0.0")

然后执行以下命令:

activator
compile
eclipse
