1.功能

將專案打jar包，從而可以在不同環境下執行。

2.步驟

（1）開啟cmd（注意，win10的powershell有些不相容，最好用cmd）

（2）進入專案根目錄

e:
cd Tools\WorkspaceforMyeclipse\WebSpring

（3）執行

 mvn clean package -DskipTests
結果：
[INFO] --- maven-surefire-plugin:2.21.0:test (default-test) @ web ---
[INFO] Tests are skipped.
[INFO]
[INFO] --- maven-jar-plugin:3.0.2:jar (default-jar) @ web ---
