When I try to compile my project I get the following exception:

我发现了相同的问题2 在Play 2问题跟踪器中，他们说，当routes文件增长时，就会出现该异常.

I found the same issue in the Play 2 issue tracker and they said that when the routes file grows it makes that exception.

因为我的项目不再编译了，所以有解决此异常的方法吗?

Is there a solution to this exception because my project doesn't compile anymore ?

我正在将Play 2.0.3用于scala(我的路由文件约为150行)

I'm using Play 2.0.3 for scala(my routes file is about 150 line)

推荐答案

我在Play 2.0.6上遇到了同样的问题.升级到Play 2.0.8，并没有帮助.然后，我修改了 $ play_dir/framework/build 脚本，使其使用 -Xss2M 而不是 -Xss1M 构建，问题消失了(我可以编译现在通常如此.

I had the same issue with Play 2.0.6. Upgraded to Play 2.0.8 and it didn't help. I then modified the $play_dir/framework/build script so it builds with -Xss2M instead of -Xss1M and the problem disappeared (I can compile normally now).
