为什么sbt会抛出“；value enablePlugins不是sbt.Project的成员；例外？

我正在尝试在使用SBT版本0.13.5的项目中启用自定义AutoPlugin。当我尝试通过以下方式在我的

build.sbt

中启用插件时：

val aProject = project.in(file("foo")).enablePlugins(MyAutoPlugin)

尝试从命令行启动SBT时，我遇到以下错误：

value enablePlugins is not a member of sbt.Project
... (big stack trace) ...
[error] sbt.compiler.EvalException: Type error in expression
[error] Use 'last' for the full log.
Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore?

当我查看sbt.Project的源代码时，我看到

enablePlugins

。这是怎么回事

编辑：当我取消调用

启用插件

时，我可以成功启动SBT会话。运行

>about

确认SBT版本为0.13.5

编辑3：我发现，当我以“2014.06.26-1-SNAPSHOT”格式将插件发布到Sonatype时，SBT无法加载，出现上述错误。但是，如果我将格式更改为在“-1”之后包含一个字母，则SBT将加载。因此，此版本格式有效：“2014.06.26-1a-SNAPSHOT”。我发现这一点是因为我发现解析到本地发布的插件似乎工作得很好（除了一个从未工作过的插件），而解析到发布到Sonatype的完全相同的插件则导致了错误。当我在本地发布时，我总是在版本中添加一封信

原来问题与发布到Sonatype快照存储库以及SBT如何解决插件有关

我按照来自的建议发布到Bintray。我也只发布发布版本（而不是快照）。现在一切正常

更新：一个简单的解决方法是在

项目/pugins.SBT

中为SBT版本添加依赖项覆盖：

// project/plugins.sbt
dependencyOverrides += "org.scala-sbt" % "sbt" % "0.13.7"

---

注意：您提供的版本应与

project/build.properties

文件中的版本相同。

您可以通过使用

project/build.scala

而不是

build.sbt

来解决此问题

---

实际问题详见和

删除ivy2缓存文件对我有用：

rm -r ~/.ivy2/

---

参考资料：

能否添加

about

命令的输出内容？能否提供再现此错误的最小工作示例？能否执行

sbt-Dsbt.global.base=/tmp/so

以删除任何可能干扰sbt 0.13.5的全局插件？您是否可能使用

addSbtPlugin（“net.virtual void”%”sbt依赖关系图“%”0.7.4“

作为插件？这导致了一些类似于您的问题。因此，我已将我们的插件升级为全部自动插件，当我添加本地发布的插件（Resolver.defaultLocal）时，一切都正常。当我发布到sonatype并使用Resolver.sonatypeRepo（“快照”）时，其中一个插件会导致SBT降级并再次抛出此错误。这个有问题的插件正在包装sbt scalriform 1.3.0，但是，请注意，将插件发布到Bintray是解决该问题的更好方法。如果使用了

，则无需移动到
.scala
版本。sbt

+这些插件将可用于任何sbt版本项目，而无需依赖其他解析程序。2016年晚些时候更新：问题仍然存在，解决方法标记提到的仍然有效
