java，为什么会出现这些错误--maven编译器插件：3.7.0

我正在浏览以下opendaylight指南：

编译过程中出现错误：

[ERROR] ...Odl-testProvider.java:[14,17] '{' expected
[ERROR] ...Odl-testProvider.java:[21,15] <identifier> expected
[ERROR] ...Odl-testProvider.java:[21,16] invalid method declaration; return type required

编译器信息：

目标：maven编译器插件：3.7.0:编译（默认编译）
编译器“javac”，源代码=1.8，目标代码=1.8

---

您必须查看Java类名允许使用的字符<代码>-是不允许的。请查看此处：

“Odl testProvider”不是有效的标识符。它是两个带有减号的标识符。。。这将混淆任何编译器。简言之：这是一个由于打字错误导致的语法错误。事实上，编译错误与maven编译器插件无关。您似乎被OpenDaylight的氧气释放所使用。只是想让你知道，你可能想使用我们刚刚发布的最新版本氟；请参阅，但请注意，
