[英]Maven not packaging dependencies with jar
I am trying to create a jar file for a java project using Maven.我正在尝试使用 Maven 为 java 项目创建 jar 文件。 Running
mvn package
creates a jar without errors however attempting to run it on the command line I get this error:运行
mvn package
创建一个 jar 没有错误但是尝试在命令行上运行它我得到这个错误:
Error: Unable to initialize main class uk.ac.ed.inf.App
Caused by: java.lang.NoClassDefFoundError: com/mapbox/geojson/Geometry
This appears to be an issue with dependencies not being added to the classpath.这似乎是依赖项未添加到类路径的问题。 I have tried a few different solutions using the maven-assembly or maven-shade but nothing seems to work.
我使用 maven-assembly 或 maven-shade 尝试了一些不同的解决方案,但似乎没有任何效果。
Here is my pom.xml:这是我的 pom.xml:

A previous answer suggests running it with mvn clean compile assemble:single
however the build fails with the error:先前的答案建议使用
mvn clean compile assemble:single
运行它,但是构建失败并出现错误:
No plugin found for prefix 'assemble' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (C:\Users\Fraser\.m2\repository), central (https://repo.maven.apache.org/maven2)] -> [Help 1]
Any help would be appreciated.任何帮助,将不胜感激。
