Question

我已经在这个项目上工作了几个月，本周我又回到了它，似乎随着PlayN和三重播放的快照发生了一些问题，因为我得到了

Exception in thread "AWT-EventQueue-0" java.lang.Error: Unresolved compilation problem:

看起来你正在使用旧版本的PlayN，它在Surface / Canvas上没有流畅的界面。

你可以运行：

mvn dependency:tree

在您的core子模块中（在该目录中），以查看正在使用哪些版本的PlayN jar文件来构建项目。以下是我的一个游戏中的示例：

[INFO] --- maven-dependency-plugin:2.1:tree (default-cli) @ atlantis-core ---                                                   
[INFO] com.threerings.atlantis:atlantis-core:jar:1.0-SNAPSHOT                                                                   
[INFO] +- com.googlecode.playn:playn-core:jar:1.1-SNAPSHOT:compile                                                              
[INFO] +- com.threerings.nexus:nexus-core:jar:1.0-SNAPSHOT:compile                                                              
[INFO] |  \- com.threerings:react:jar:1.1:compile                                                                               
[INFO] +- com.threerings:tripleplay:jar:1.1-SNAPSHOT:compile                                                                    
[INFO] +- com.samskivert:pythagoras:jar:1.2-SNAPSHOT:compile                                                                    
[INFO] +- com.google.guava:guava:jar:10.0:compile                                                                               
[INFO] |  \- com.google.code.findbugs:jsr305:jar:1.3.9:compile                                                                  
[INFO] \- junit:junit:jar:4.8.1:test

如果你没有看到playn-core：jar：1.0.1或1.0.2，（如果你是根据你自己的PlayN版本建立的话，还是1.1-SNAPSHOT），那么有些不对劲。您最有可能通过直接向您的core/pom.xml添加playn-core依赖来补救所述不幸事件。通常，您的顶级pom.xml将定义您在项目中使用的PlayN版本：

<properties>
  <playn.version>1.0.2</playn.version>
</properties>

然后您的core/pom.xml将使用该属性声明playn-core依赖项：

<dependency>
  <groupId>com.googlecode.playn</groupId>
  <artifactId>playn-core</artifactId>
  <version>${playn.version}</version>
</dependency>

使用PlayN + tripleplay完成未解决的编译
