使用Jenkins打包docker镜像时报这个错，并且还是在有别的项目正常打包的情况下，新建的任务就不好使了。
完整的错误信息：

产生此异常的原因就是因为Jenkins创建任务的时候，任务名中包含了大写字母或者是DockerFile里面配置的镜像名称和路径跟任务配置中的不一致。
第一点，看这里，这个任务名称，不能包含大写字母。
你要说不支持大写字母，Jenkins 在创建任务的时候，就该提示了对吧，其实并没有，因为这个不是Jenkins的锅，因为使用maven打包项目也是正常的。
那么问题在哪呢？？？？？？ rnmmp，我找了一上午，没找到在哪。。。。。。。
最后实在没办法了，我直接在项目文件夹下手动执行构建镜像，也就是使用docker build
看下操作日志：
[root@docker-manager-40-37 providerB]# ls
Dockerfile pom.xml src target
[root@docker-manager-40-37 providerB]# pwd
/usr/soft/jenkins_home/workspace/providerB
[root@docker-manager-40-37 providerB]# ll

[root@docker-manager-40-37 providerB]# docker build -t 192.168.40.37:5000/jadl/providerb:1.0_t0
"docker build" requires exactly 1 argument.
See 'docker build --help'.
Usage: docker build [OPTIONS] PATH | URL | -
Build an image from a Dockerfile
[root@docker-manager-40-37 providerB]# docker images
这里面非常非常关键的一个提醒就是：repository name must be lowercase，镜像仓库里面的镜像名称必须为小写字母，就很迷？？？是不是。。。。
但是呢，我执行完之后，并没有在意，因为到中午吃饭时间了。。。。。
午休过后，又开始倒腾这个，然后发现这个路径的名称是包含大写字母的，试着改一下吧，改成小写的，将providerB 改为 provider_b, 顺带把任务里面的配置也给一块改了。
以及Dockerfile里面的jar的名称，也给改成下划线的了。
再次构建，竟然好了？？？？困扰一上午了。。。。
