How to make a "fat jar" of a Maven project?
提问by daniels
Using IntelliJ I just created a new Maven project and added the following to the pom file http://undertow.io/downloads.htmland the following to a Main.java file http://undertow.io/index.html
使用 IntelliJ 我刚刚创建了一个新的 Maven 项目并将以下内容添加到 pom 文件http://undertow.io/downloads.html并将以下内容添加到 Main.java 文件http://undertow.io/index.html
Now if I run the code all works well, but how do I make this as a "fat jar" that will contain all the dependencies in the pom file and that I'll be able to run by just java -jar my.jar? Like you are able to do with a Spring Boot app.
现在，如果我运行代码一切正常，但是我如何将它作为一个“fat jar”来包含 pom 文件中的所有依赖项，并且我只能通过它运行java -jar my.jar？就像您可以使用 Spring Boot 应用程序一样。

Maven Shade Plugindoes this well.
Maven Shade Plugin在这方面做得很好。

<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.4.3</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<transformers>
<transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>package.Main</mainClass>
</transformer>
</transformers>
</configuration>

1) Add the Spring-boot-maven-pluginto the pom.xml file
1）Spring-boot-maven-plugin在pom.xml文件中添加
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>1.4.0.RELEASE</version>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
2) Change the packing to jar
2) 将包装改为 jar
<packaging>jar</packaging>
3) mvn packagewill create the executable jar.
3)mvn package将创建可执行jar。
