[英]one jar with one class and main class from dependecy jar
我在一个项目中有两个名为Test1和Test2的类 。
Test1和Test2都不是主要类。 现在,我有一个名为cloudexe.jar的依赖项 ,它具有一个主类ClassExecuter 。 现在我的问题是我希望ClassExecuter作为test1.jar和test2.jar的主类。
test1.jar应该仅包含Test1类及其所有依赖关系,包括cloudexe.jar同样, test2.jar应该仅包含Test2类及其所有依赖关系,包括cloudexe.jar
现在,当我打包我的pom.xml时,我得到了test1.jar和test2.jar,但是我得到的结果如下图所示
Exception in thread "main" java.lang.NoSuchMethodException: com.uber.Test1.main([Ljava.lang.String;)
at java.lang.Class.getMethod(Class.java:1678)
at com.simontuffs.onejar.Boot.run(Boot.java:339)
at com.simontuffs.onejar.Boot.main(Boot.java:166)
我的pom.xml在下面给出
<build>
<plugins>
<plugin>
<groupId>com.jolira</groupId>
<artifactId>onejar-maven-plugin</artifactId>
<version>1.4.4</version>

有人可以帮我吗
您需要有一个带有2个子项目的父母:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.example</groupId>
<artifactId>parent</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>pom</packaging>
<modules>
<module>test1</module>
<module>test2</module>
</modules>
</project>
然后,您有2个项目test1和test2项目,它们将生成jar,使用阴影插件使其执行主类ClassExecuter:
