我遇到了类似的情况，但是用 -D 覆盖不是解决方案(只是不要问)，因为我有一些变量，配置文件也没有.

I was kind of in a similar situation, but an override with -D is no solution (just don't ask) and since I've got a few variables, profiles are none either.

就我而言，它是这样的:fabric8 docker maven 插件使用一个变量.该变量由build-helper-maven-plugin"正则表达式属性生成.

In my case it's like this: The fabric8 docker maven plugin uses a variable. That variable is generated by the "build-helper-maven-plugin" regex-property.

如果调用了mvn docker:build"，则不会使用验证阶段并且变量不存在(所以我得到一个${blabla}"文字)并且构建失败.如果我调用通常的构建，就会创建变量.

If "mvn docker:build" is invoked, the validate phase is not used and the variable is not there (so I get a "${blabla}" literal) and the build fails. If I invoke the usual build, the variable gets created.

我采取了运行mvn validate docker:build"而不是mvn docker:build"的策略来强制执行验证步骤，因此创建了变量.

I took the strategy to run "mvn validate docker:build" instead of "mvn docker:build" to force the validation step, so the variable gets created.
