我将Play 2.2.3与Java和sbt.version=0.13.5一起使用。
当我运行play clean compile时，我可以看到：
[success] Total time: 0 s, completed Aug 27, 2014 3:12:26 PM
但当我在Heroku上运行sbt compile stage或deploy或仅运行sbt clean compile时，会生成以下消息：

为什么？如何解决此问题？
根据错误消息，解析pom-http://repo1.maven.org/maven2/org/kie/kie-parent-with-dependencies/6.1.0.Final/kie-parent-with-dependencies-6.1.0.Final.pom，特别是部分
<dependency>
<groupId>org.jboss.dashboard-builder</groupId>
<artifactId>dashboard-builder-bom</artifactId>
<type>pom</type>
<version>${dashboard-builder.version}</version>
<scope>import</scope>
</dependency>
已经报道的案例很少，使用Maven的高级功能解析更复杂的pom会导致sbt失败（需要引用）。
问题似乎是由于缺少依赖项的解析程序造成的。在build.sbt中添加以下内容：
resolvers += "jboss-releases" at "https://repository.jboss.org/nexus/content/repositories/releases"
