带有依赖项的java Maven可执行JAR
我有一个mvn项目，其中包含对apache commons-lang3的依赖。我设法生成了一份清单。它通过java-jar启动。我远程服务器上的jar。 然而，它不包含任何依赖项，我不知道为什么
这是pom。xml位于/workspace/：

gitlab CI文件如下所示：

variables:
# This will suppress any download for dependencies and plugins or upload messages which would clutter the console log.
# `showDateTime` will show the passed time in milliseconds. You need to specify `--batch-mode` to make this work.
MAVEN_OPTS: "-Dhttps.protocols=TLSv1.2 -Dmaven.repo.local=$CI_PROJECT_DIR/.m2/repository -Dorg.slf4j.simpleLogger.log.org.apache.maven.cli.transfer.Slf4jMavenTransferListener=WARN -Dorg.slf4j.simpleLogger.showDateTime=true -Djava.awt.headless=true"
# As of Maven 3.3.0 instead of this you may define these options in `.mvn/maven.config` so the same config is used
# when running from the command line.
# `installAtEnd` and `deployAtEnd` are only effective with recent version of the corresponding plugins.

当这个作业运行完后，我会得到一个jar文件，其中包含以下清单。MF:
Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Created-By: Apache Maven 3.6.3
Built-By: root
Build-Jdk: 11.0.10
Class-Path: libs/commons-lang3-3.11.jar
Main-Class: com.hohmannit.phdev.midi.App
您可以看到，它正确地解析了对commons lang的依赖，并将其放入清单中。但实际的文件丢失了
有人知道为什么吗
# 1 楼答案
我认为你的maven jar插件正在向清单中添加条目。然而，它并不与依赖项捆绑在一起
尝试添加以下插件
