如何使用 sbt-eclipse 创建项目的 Eclipse 项目文件?

2022-01-24 00:00:00 macos scala eclipse sbt

我按照官方文档在我的sbt项目中设置插件:

I followed the official documentation to set up the plugin in my sbt project:

添加 addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" %"2.5.0") 到 ~/.sbt/plugins/plugins.sbt 文件
cded 到一个项目并运行 sbt
在 sbt shell 中，输入 eclipse

Added addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "2.5.0") to ~/.sbt/plugins/plugins.sbt file

cded to a project and ran sbt

In sbt shell, typed eclipse

这就是我遇到以下错误的地方:

That's where I faced the following error:

> eclipse [error] Not a valid command: eclipse (similar: help, alias) [error] Not a valid project ID: eclipse (similar: sbteclipse) [error] Expected ':' (if selecting a configuration) [error] Not a valid key: eclipse (similar: deliver, licenses, clean) [error] eclipse [error] ^

我错过了什么?

提前感谢您能给我的任何帮助.

Thanks in advance for any help you can give me.

推荐答案

我使用的是 sbt 0.13.5.

I'm using sbt 0.13.5.

$ sbt --version sbt launcher version 0.13.5

在 empty 目录中执行 sbt about 以检查 build/sbt 设置.

In an empty directory executed sbt about to check the build/sbt setup.

$ sbt about [info] Loading global plugins from /Users/jacek/.sbt/0.13/plugins [info] Updating {file:/Users/jacek/.sbt/0.13/plugins/}global-plugins... [info] Resolving org.fusesource.jansi#jansi;1.4 ... [info] Done updating. [info] Set current project to sbteclipse (in build file:/Users/jacek/sandbox/sbteclipse/) [info] This is sbt 0.13.5 [info] The current project is {file:/Users/jacek/sandbox/sbteclipse/}sbteclipse 0.1-SNAPSHOT [info] The current project is built against Scala 2.10.4 [info] Available Plugins: sbt.plugins.IvyPlugin, sbt.plugins.JvmPlugin, sbt.plugins.CorePlugin, sbt.plugins.JUnitXmlReportPlugin, net.virtualvoid.sbt.graph.Plugin, com.timushev.sbt.updates.UpdatesPlugin [info] sbt, sbt plugins, and build definitions are using Scala 2.10.4

目录中没有文件(忽略 target，因为它是 sbt 在启动时自动创建的，可以随时删除).

No files are in the directory (disregard target since it's automatically created by sbt upon startup and can be removed at any time).

$ tree . `-- target 1 directory, 0 files

然后我用 sbt 运行 sbt shell 以确保不存在 eclipse 命令.

I then ran the sbt shell with sbt to ensure no eclipse command existed.

$ sbt [info] Loading global plugins from /Users/jacek/.sbt/0.13/plugins [info] Set current project to sbteclipse (in build file:/Users/jacek/sandbox/sbteclipse/) > eclipse [error] Not a valid command: eclipse (similar: help, alias) [error] Not a valid project ID: eclipse (similar: sbteclipse) [error] Expected ':' (if selecting a configuration) [error] Not a valid key: eclipse (similar: deliver, licenses, clean) [error] eclipse [error] ^

我可以重现您的问题.继续设置插件 - 我确实没有关闭 sbt shell.

I could reproduce your issue. Moving on to setting up the plugin - I did not close the sbt shell.

按照文档我打开 ~/.sbt/0.13/plugins/plugins.sbt 得到它如下:

Following the documentation closely I opened ~/.sbt/0.13/plugins/plugins.sbt to have it as follows:

$ cat ~/.sbt/0.13/plugins/plugins.sbt addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "2.5.0")

使用文件中的插件，我在 sbt shell 中触发了 reload 以加载更改.

With the plugin in the file, I fired reload in the sbt shell to load the changes.

> reload [info] Loading global plugins from /Users/jacek/.sbt/0.13/plugins [info] Updating {file:/Users/jacek/.sbt/0.13/plugins/}global-plugins... [info] Resolving org.fusesource.jansi#jansi;1.4 ... [info] Done updating. [info] Set current project to sbteclipse (in build file:/Users/jacek/sandbox/sbteclipse/) > eclipse [info] About to create Eclipse project files for your project(s). [info] Updating {file:/Users/jacek/sandbox/sbteclipse/}sbteclipse... [info] Resolving org.fusesource.jansi#jansi;1.4 ... [info] Done updating. [info] Successfully created Eclipse project files for project(s): [info] sbteclipse

如您所见，插件已正确加载并生成文件.按照步骤操作，您应该可以顺利安装插件.

As you can see the plugin was properly loaded and generated the files. Follow the steps and you should have the plugin installed with no issues.
