Question

我正在尝试使用命令mvnw install dockerfile:build构建我的第一个Docker映像，但是出现以下错误：

Could not find goal 'build' in plugin org.apache.maven.plugins:maven-dependency-plugin:3.0.2 
among available ....

，并且有可用的“目标”列表。构建不存在，但是存在构建类路径，因此我尝试使用它，然后出现错误：

Could not find goal 'build-classpath' in plugin com.spotify:dockerfile-maven-plugin:1.4.9 among available goals build, help, push, tag

所以这两个命令都不起作用。我正在使用Windows，这是我的POM：

我正在使用“构建”目标的地方。怎么了？

Answer 1

您正在配置goals中的build和push和dockerfile-maven-plugin，它们实际上是maven-dependency-plugin上的dockerfile-maven-plugin。将这些目标降低到{{1}}，然后重试。

如果尚未发生，您也可以遵循此quite basic example。

mvnw install dockerfile：build failed在插件中找不到目标“ build”
