Jenkins Master Salve 部署的包 jar md5sum 值不一样

如何解决Jenkins Master Salve 部署的包 jar md5sum 值不一样

Master:
Parsing POMs
Established TCP socket on 35356
[workspace] $ /var/www/dream/jdk/bin/java -cp 
/var/www/dream/.jenkins/plugins/maven-plugin/WEB-INF/lib/maven33-agent-1.13.jar
/var/www/dream/apache-maven-3.3.9/boot/plexus-classworlds-2.5.2.jar:

/var/www/dream/.jenkins/plugins/maven-plugin/WEB-INF/lib/maven3-interceptor-commons-1.13.jar 
Salve:

/data/jenkins-salve/remoting.jar 
/data/jenkins-salve/maven33-interceptor.jar 
/data/jenkins-salve/maven3-interceptor-commons.jar

问题是git repo相同的代码相同的分支怎么才能得到相同的md5sum值

[root@jenkins-salve lib]# md5sum /var/www/dream/.jenkins/workspace/testxxx_platform_im-observer/target/im-observer.jar
045d1f6ecbc74e12ffd6c49d3f37e656  /var/www/dream/.jenkins/workspace/testxxx_platform_im-observer/target/im-observer.jar
[root@localhost logging]# md5sum /var/www/dream/.jenkins/jobs/dev_platform_imobserver/workspace/target/im-observer.jar
9ffe50083509841fb29f050cb81c489b  /var/www/dream/.jenkins/jobs/dev_platform_imobserver/workspace/target/im-observer.jar

请帮助我寻找这个床问题 thks!!!
