Jenkins 参数集成
仍然登录到Jenkins web管理页，点击新建任务。
添加描述信息
点击“参数化构建过程”
#!/bin/sh echo "Current deploy environment is $deploy_env"
echo "The build is $version"
echo "The paasword is $pass" if $bool
then
echo "Request is approved"
else
echo "Request is rejected"

新建一个空的Java-war-dev工程，复制其仓库地址；
然后切到windows git bash命令行，上传本地代码到刚才新建的Java-war-dev仓库中：

查看gitlab上已经上传成功，复制Java-war-dev仓库地址；
再次回到Jenkins刚才创建的maven-freestyle-job中，将复制的仓库地址粘贴过来；
接着添加构建步骤
返回到Jenkins系统管理设置jdk和maven路径
点击“Apply”,最后点击“Save”
回到Jenkins mavent-freestyle-job配置页；
试了好多次，中间错误过程及错误信息在本文结尾列出，针对我的环境，我猜测的是路径错误导致的，因为重新设置了路径之后，第16次构建，也就是上述构建成功的截图就是我重新建了一个Java-war-dev工程，直接在工程下面就是src目录，之前的错误因为我的目录结构是Java-war-dev工程下还有一个Java-war-dev文件夹，导致一直报错，在晚上转了一大圈，也没解决，最后我尝试新建了一个工程，重新配置了一下，构建成功！

The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
NB: JAVA_HOME should point to a JDK not a JRE
Build step 'Invoke top-level Maven targets' marked build as failure
Finished: FAILURE
由报错信息可以看出，jdk环境设置有问题
以下报错信息目前没有解决掉，如果有热心同学知道解决办法的欢迎评论区指教^_^ ~,针对以上问题，我是删掉重新构建了一遍，包括全局凭据也是删掉重新创建了一个一样的，然后再次执行的时候就没有报错。
但是经反复确认，jdk路径没有错，接着有重新构建，提示以下内容
