(1)编译打包
mvn clean scala:compile compile package
mvn clean scala:compile compile assembly:single

(2)run,on windows
java -cp hello-1.0-SNAPSHOT.jar;c:\scala\lib\* com.huawei.xdba.HelloWorld

(4)intellij开发注意设置源文件夹,否则报ClassNotFoundException
Go to the menu File > Project Structure. Click the "Modules" section, then click your module name, then click the "Sources" tab.	


(5)maven报错
Caused by: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
解决办法：
(1)用浏览器访问https://repo.maven.apache.org/maven2/，导出证书保存为maven1.cer
(2)keytool -import -alias mavenrootkeysore -keystore "C:\Java\jdk1.8.0_73\jre\lib\security\cacerts" -file D:\maven1.cer
