Question

我有三个apache-camel项目，比方说project-A，project-B和project-C。 project-A有java main方法，它依赖于project-B而project-B依赖于project-C（project-C的依赖项在project-B中添加，project-B依赖项在project-A中添加）。我想为project-B创建jar文件。我试图通过在project-A的pom.xml -

中放置以下配置来创建jar文件

我面临的问题：在项目-B和项目-C中，我有两个同名的文件，因此在创建jar文件后，一个文件被另一个文件覆盖。任何帮助将非常感激。

让父项目同时构建所有3个项目：

<?xml version="1.0" encoding="UTF-8"?>
<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.greg</groupId>
  <artifactId>example</artifactId>
  <version>1.0-SNAPSHOT</version>
  <packaging>pom</packaging>

  <name>example</name>

  <modules>
    <module>project-a</module>
    <module>project-b</module>
    <module>project-c</module>
  </modules>

</project>

每个项目都可以根据需要具有本地项目依赖关系，project-b pom.xml将如下所示：

<?xml version="1.0"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>

  <parent>
    <groupId>com.greg</groupId>
    <artifactId>example</artifactId>
    <version>1.0-SNAPSHOT</version>
  </parent>

  <artifactId>project-b</artifactId>

  <dependencies>
    <dependency>
      <groupId>com.greg</groupId>
      <artifactId>project-c</artifactId>
      <version>${project.version}</version>
    </dependency>
  </dependencies>

 <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-shade-plugin</artifactId>
                <version>3.0.0</version>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>shade</goal>
                        </goals>
                        <configuration>
                            <transformers>
                                <transformer                                            implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                    <manifestEntries>
                                        <Main-Class>com.greg.Application</Main-Class>
                                    </manifestEntries>
                                </transformer>
                            </transformers>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

        </plugins>
    </build>

</project>

将创建一个在project-b / target-1.0-SNAPSHOT.jar中运行main方法com.greg.Application的executbale jar

从多个项目创建JAR文件，相互依赖
