Playframework Play framework在以下位置启动时挂起："；从“加载项目定义”；

我刚刚开始使用Play框架。我已经下载并安装了play，并创建了一个示例java应用程序。当我尝试在应用程序目录中启动播放控制台时，它挂起在“加载项目定义”处

当我尝试运行Scala应用程序时，会收到一条消息，说明它正在等待锁定：

PS C:\dev\play\scalatest> play
[info] Loading project definition from C:\dev\play\test1\project
Waiting for lock on C:\lib\play\repository\.sbt.ivy.lock to be available...

---

运行Windows 7、JDK 1.7.0_05和Play Framework 2.0.2。有什么想法吗？

我自己在Play 2中也经历过这种情况，结果证明它并不是真正的挂起，只是拉了一个专家，然后下载了互联网。要验证这与您所经历的行为相同，请编辑

project/plugins.sbt

并替换：

logLevel := Level.Warn

与

---

（虽然我是在OSX上构建的，但我想您在Windows上也会遇到类似的输出。）

尝试中止构建，删除引用的锁文件，然后再次执行“播放运行”。

只需添加到现有答案中

在我从Play 2.2x升级到Play 2.3.x之后，我也看到了这种行为（请参阅）

我调试如下

在Linux上，转到项目文件夹，然后：

$ bash -x `which sbt`
.... OUTPUT SKIPPED....
++ ((  128 < 512  ))
++ local 'common_opts=-Xms1024m -Xmx1024m -XX:ReservedCodeCacheSize=128m'
++ [[ 1.7.0_55 < 1.8 ]]
++ local perm=256
++ echo '-Xms1024m -Xmx1024m -XX:ReservedCodeCacheSize=128m -XX:MaxPermSize=256m'
+ execRunner java -Xms1024m -Xmx1024m -XX:ReservedCodeCacheSize=128m -XX:MaxPermSize=256m -jar /usr/share/sbt-launcher-packaging/bin/sbt-launch.jar

+ java -Xms1024m -Xmx1024m -XX:ReservedCodeCacheSize=128m -XX:MaxPermSize=256m -jar /usr/share/sbt-launcher-packaging/bin/sbt-launch.jar

最后，我还在

project/plugins.sbt

中添加了

logLevel:=Level.Debug

但是，它不断提供如下输出：

要下载的JAR似乎太多了。我现在使用的是离线版本的Typesafe Activator（356MB下载），这要快得多

+1因为当我读完这篇文章时，我的互联网已经完全下载，我的项目开始了。值得注意的是，IntelliJ 13的最新版本支持sbt项目[适用于Scala Play项目]这意味着同时使用控制台sbt会话和IntelliJ会导致大量的

ivy.lock

等待消息，因为这两个环境在解决依赖关系时竞争更新ivy repo。解释清楚。谢谢。此回复中的调试说明非常有用。我使用

bash-x“$（哪个sbt）”

发现

http.proxyHost

和

http.proxyPort

正在从环境中拾取，导致工件解析失败（由于sbt回购是公司内部的，因此确实需要不通过代理）。非常感谢。
