Question

这可能是一个，但是，但可能是我，我错过了一步，或者什么都不懂。

我正在尝试在Maven项目中设置一个专用子模块，唯一的任务是生成docker映像（这是一个用于测试的测试项目，但可能会将结构用于其他用途）。但是，每次尝试构建子模块时，都会出现错误“无法解析com.spotify：dockerfile-maven-extension：1.4.3的插件描述符”。

我试图用各种尺寸的锤子砸行家，但是我似乎无法破解。我确实发现执行mvn deploy和mvn dockerfile:build之间是有区别的。如果执行mvn deploy，我会遇到上述错误，但是执行mvn dockerfile:build不会出现任何问题，并且会按预期生成一个docker映像。我也尝试过从源代码构建扩展，但是如果集成测试失败。手动运行某些测试（同时尝试了高级和多模块测试）会导致与我在自己的项目中看到的相同错误。

如何繁殖

站在子模块中，执行mvn deploy

您期望什么

我希望mvn deploy和mvn dockerfile:build都能产生docker映像

发生了什么事

如果我执行mvn dockerfile:build，它将产生没有任何问题的图像。如果我改为执行mvn deploy，它将崩溃并显示错误消息：“无法解析com.spotify的插件描述符：dockerfile-maven-extension：1.4.3（C：\ Users \ mcso.m2 \ repository \ com \ spotify \ dockerfile-maven-extension \ 1.4.3 \ dockerfile-maven-extension-1.4.3.jar）：在META-INF / maven / plugin.xml-> [Help 1]中找不到插件描述符。” >

软件：

docker version：18.03.1-ce
Spotify的dockerfile-maven版本：1.4.3

Answer 1

dockerfile-maven-extension不是maven插件，而是maven扩展。

因此，请勿在{{1}}的{{1}}部分中使用它，而应在<build><plugins>内使用它

pom.xml

（来源：Dockerfile Maven readme on GitHub）

由于您已经在父pom中执行了此操作，因此应该只需从子pom中删除相应的<build><extensions>元素即可。

Maven无法找到com.spotify：dockerfile-maven-extension：1.4.3
