无法导出播放！ 应用程序为战争
我正在尝试打包Play！ 针对Java 7构建的应用程序。我遇到此错误。 另外，我无法从命令行启动应用程序，但是它可以从Eclipse中运行。
D:DropboxeclipseProjectsClassic>play war MyApp -o MyApp.war --zip

更新我已经通过将JAVA_HOME系统变量更改为jdk7目录解决了UnsupportedClassVersionError。 IOError仍然会出现。
UPDATE2通过将输出目录更改为“C： MyApp.war”来解决IOError问题
如果我从Play 1.2.4RC1的发行说明中理解正确，那么Play 1.2.3没有完整的Java 7支持。 试用Play架构下载页面中的新的Play 1.2.4发布候选版本吗？ 它的发行说明告诉我们“现在支持Java 7的开箱即用”。
