Question

我正在尝试运行我从git clone https://github.com/djonmayer/play21-osm.git获得的播放项目的克隆

我安装了2.2.2版本和scala版本2.10.4。

当我在项目克隆到的目录中键入play时，我收到以下错误：

java.lang.NoSuchMethodError: scala.Predef$.augmentString(Ljava/lang/String;)Lscala/collection/immutable/StringOps;
    at sbt.ConsoleLogger$.<init>(ConsoleLogger.scala:129)

    at xsbt.boot.Boot.main(Boot.scala)
Error during sbt execution: java.lang.NoSuchMethodError: scala.Predef$.augmentString(Ljava/lang/String;)Lscala/collection/immutable/StringOps;

如果我运行play clean，情况就是如此。我已经读过这可能是一个依赖项问题所以我尝试将行scalaVersion := "2.10.4"添加到Build.scala的play.Project.settings部分并单独添加到build.sbt文件中。它没用。

Answer 1

我试着把它放在评论中，但这是不可读的。

谢谢，zeppaman。看起来这个问题与运行在旧版Play中创建的Play Framework项目有关。通过查看已提交升级到新游戏版本的另一个项目，我做了以下更改。

在build.properties中：

sbt.version=0.12.2

成为：

sbt.version=0.13.0

在plugins.sbt中：

addSbtPlugin("play" % "sbt-plugin" % "2.1.1")

成了：

addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.2.2")

这使我能够进行更新然后抛出错误：

[error] Modules were resolved with conflicting cross-version suffixes in {file:/Users/michaelrichardson/Documents/Play/play21-osm/}play21-osm:
[error]    org.scala-stm:scala-stm _2.10, _2.10.0
[trace] Stack trace suppressed: run last *:update for the full output.
[error] (*:update) Conflicting cross-version suffixes in: org.scala-stm:scala-stm

我在Build.scala中更改了一行：

    "com.typesafe.play" %% "play-slick" % "0.3.2"

成了：

    "com.typesafe.play" %% "play-slick" % "0.5.0.2-SNAPSHOT"

EXTRA：这会将错误更改为：

更新：解决了未解决的依赖

依赖性未解决的问题似乎可能是由于我的本地sbt / ivy存储库被破坏了。见unresolved dependency: com.typesafe.play#play-slick_2.10;0.6.0.1: not found

Answer 2

这类问题通常与两个类似的问题有关：

缺少同一类的jar
同一个班级进入多个罐子

因此，请检查scala和play版本是否兼容，以及是否已包含已包含缺少方法的类的jar。

运行“play”时会发生java.lang.NoSuchMethodError
