問題1，
[ERROR]Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.21.0:test (default-test) on project motherBuyBoot: There are test failures.
[ERROR] Please refer to D:\web\motherbuy\target\surefire-reports for the individual test results. [ERROR] Please refer to dump files (if any exist) [date]-jvmRun[N].dump, [date].dumpstream and [date]-jvmRun[N].dumpstream.
f方法：pom,xml 文件的Junit版本不對，或者其他原因，我將junit依賴注釋掉，編譯通過；親測有效。
問題2，
Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.7.0:compile (default-compile) on project motherBuyBoot: Compilation failure
[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?
方法：由此聯想到compile編譯環境的問題，是沒有配置好；看圖解決，別忘了update maven
