第一个问题：
要更新一个微服务，需要打jar包上传给运维，结果报错了
Cannot get the revision information from the scm repository组长说是svn的bin目录下缺少svn.exe
原因是安装的时候没有选这一项：
将红叉那里的选项换成command line client tools就会有svn.exe了，环境变量里也自动配好了。
第二个问题：
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project in-study: Compilation failure
[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?解决方案：https://blog.csdn.net/lslk9898/article/details/73836745
