Best practices when creating 2 Jars (Portable and Dependency) in Maven
问题
我创建了一个小工具来签署PDF文件。现在我想要有两个JAR文件，一个是便携式的JAR文件，只需执行该JAR文件即可，另一个JAR文件可以加载到其他项目中并使用。
我的当前方法：
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>3.3.0</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
<configuration>
<finalName>BatchPDFSign</finalName>
<archive>
<manifest>
<mainClass>BatchPDFSign.Main</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<appendAssemblyId>false</appendAssemblyId>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.1</version>
</plugin>
</plugins>
</build>
正如你所看到的，我的第一种方法是使用maven-assembly-plugin创建一个Uber Jar，并使用maven-compiler-plugin创建普通的Jar。
但我觉得我可能做错了，有更好的方法可以做到这一点。我在Maven中还比较新手。
简而言之：有没有一种最佳方法可以一次性创建一个包含所有依赖项的Jar和一个适用于上传到Maven的Jar？

I created a small tool to sign PDF's. Now I would like to have 2 Jars, one Portable Jar where you can just execute the Jar and thats it and a Jar which can be loaded into other projects and used.
My current approach:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>3.3.0</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
<configuration>
<finalName>BatchPDFSign</finalName>
<archive>
<manifest>
<mainClass>BatchPDFSign.Main</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<appendAssemblyId>false</appendAssemblyId>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.1</version>
</plugin>
</plugins>
</build>
As you can see my first approach was to create an Uber Jar with the maven-assembly-plugin and the normal Jar with the maven-compiler-plugin.
But I don't loose the feeling that I've done it totaly wrong and there is a much better way to do this. I am quite new with maven.
tl;dr: what is the best way to create a Jar with all the dependencies and a Jar suitable to be uploaded to maven in one swoop?

得分: 2
通常情况下，您会创建一个具有两个模块的多模块项目：
- 库模块。
- 可执行的JAR 模块。
可执行的JAR 模块将库模块作为依赖项，并添加运行所需的内容（可能包括一个主类和一些配置）。
然后，其他人也可以使用该库模块。
英文:
Usually, you would create a multi-module project with two modules:
- The library.
- The executable jar.
The executable jar uses the library as dependency and adds what is needed to run it (probably a Main class and some configuration).
Then the library can also be used by anybody else.
