Question

在maven中看到编译错误。检查并尝试了我从谷歌和堆栈*网站获得的所有变通办法。但我仍然无法解决。

已安装的maven 3.3.3及其支持的java版本1.7。请注意我还没有设置JAVA_HOME，M2和M2_HOME环境变量。但仍然走这条路。

Apache Maven 3.3.3 (7994120775791599e205a5524ec3e0dfe41d4a06; 2015-04-22T07:57:37-04:00)
Maven home: /usr/local/apache-maven-3.3.3
Java version: 1.7.0_85, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-1.7.0-openjdk-1.7.0.85.x86_64/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "2.6.32-573.3.1.el6.x86_64", arch: "amd64", family: "unix"

错误是

在这里走出困境......但App.java的第1行包含以下包定义：

package hg-groupid;

如果是这样，问题与包名中的连字符有关 - 不允许Java标识符在其名称中包含连字符 - 您可能希望将其更改为下划线。
