java - 使用 maven-dependency-plugin 使用 maven 3.1 创建可运行的 jar 不会创建可运行的 jar

Question

使用 Maven 3.1
eclipse 太阳神

看点:

尝试使用 maven-jar/dependency-plugins 创建一个可运行的 jar 文件。

问题:创建 jar 文件和依赖项后，当我尝试使用命令启动 jar 文件时出现 NoCLassDefFoundErrors

  java -jar program.jar

但是类/文件在 ./dependency-jars 文件夹中可用？？？我还尝试了以下命令:

  java -cp ./dependency-jars -jar program.jar

这也行不通。

问题:

你知道为什么jvm找不到这些类吗？怎么了？

最后一个“行”作为行分隔符。 MANIFEST.MF 文件看起来有点损坏，不是吗？

不确定发生了什么，但这是我使用 shade 构建可运行 jar 的 pom 的样子:
