Play framework 2.7.2迁移，BodyPrasers.parse NoClassDefFoundError
Play framework 2.7.2 migration, BodyPrasers.parse NoClassDefFoundError
最近我正在尝试将我们应用程序的播放版本从 2.3.x 升级到 2.7.2。我正在为 运行 的应用程序使用 netty-server。
我能够制作应用程序，running.But 当我提交简单的 http GET 请求时，它失败并出现以下错误：
play.api.UnexpectedException: Unexpected exception[ExecutionError: java.lang.NoClassDefFoundError: Lplay/api/mvc/BodyParsers$parse$;]
我曾寻找相关性以查看是否有任何其他库正在使用旧版本的游戏，但我发现 none。

我们的模块中使用了这个库 https://github.com/kenshoo/metrics-play v2.4.4 & https://github.com/pygmalios/reactiveinflux（依赖于 play 2.3.10），它与新的 play 版本 2.7.2 不兼容。因此它抛出了运行时异常。
mvn dependency:tree 可以帮助在升级时检测不兼容的库。
