这是我执行此操作的方式

mvn clean install

这是构建输出的最后几行。

  • 为什么第二个 jar (driver.jar) 没有版本化 (driver-1.1.6.jar) ？
  • 为什么本地仓库中没有安装第二个 jar？

这该怎么做？

我的要求是创建两个罐子testjar-${project.version}.jar driver-${project.version}.jar并将这两个安装在两个不同的工件中

/home/mycp/.m2/repository/com/test/te/testjar /${project-version}/testjar-${project.version}.jar _ _

/home/mycp/.m2/repository/com/test/te/ driver /${project-version}/ driver-${project.version}.jar

为什么第二个 jar (driver.jar) 没有版本化 (driver-1.1.6.jar) ？

那是因为你明确告诉maven-jar-plugin它它的名字应该driver是<finalName>driver</finalName>. 如果要附加版本，则需要具有以下配置：<finalName>driver-${project.version}</finalName>.

为什么本地仓库中没有安装第二个 jar？

那是因为你指定了一个阶段<phase>install</phase>，所以它会在执行之后default-install执行，也就是将 artefact 安装到本地仓库的执行。相反，您应该将该执行绑定到package阶段。

这是您应该为maven-jar-plugin. 需要一个分类器来创建另一个 jar。

<execution>
  <id>drive</id>
  <goals>
    <goal>jar</goal>
  </goals>
  <phase>package</phase>
  <configuration>
    <finalName>driver-${project.version}</finalName>
    <classifier>classifier</classifier>
    <includes>
      <include>com/test/te/p1/*.java</include>
      <include>com/test/te/p1/*.class</include>
    </includes>
  </configuration>
</execution>

作为旁注，我注意到您还在<resources>POM 中配置了一个元素，包括 Java 和 conf 文件。你不应该有那个。更具体地说：所有资源都应该src/main/resources放在src/main/java. 那么就不需要那个配置了。

根据评论，如果您无法添加分类器，则必须删除maven-jar-plugin并maven-assembly-plugin改用。这是一个简单的程序集描述符，可以帮助您入门。将此文件放在src/main/assembly/assembly.xml.

<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3 http://maven.apache.org/xsd/assembly-1.1.3.xsd">
    <id>driver</id>
    <formats>
        <format>jar</format>
    </formats>
    <includeBaseDirectory>false</includeBaseDirectory>
    <dependencySets>
        <dependencySet>
            <useProjectArtifact>true</useProjectArtifact>
            <unpackOptions>
                <includes>
                    <include>com/test/te/p1/*.class</include>
                </includes>
            </unpackOptions>
            <unpack>true</unpack>
        </dependencySet>
    </dependencySets>
</assembly>

在 POM 中使用以下配置：

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.5.5</version>
    <configuration>
        <descriptors>
            <descriptor>src/main/assembly/assembly.xml</descriptor> <!-- point to the location of the assembly.xml file in your project structure -->
        </descriptors>
        <appendAssemblyId>false</appendAssemblyId>
        <finalName>driver-${project.version}</finalName>
    </configuration>
    <executions>
        <execution>
            <phase>prepare-package</phase>
            <goals>
                <goal>single</goal>
            </goals>
        </execution>
    </executions>
</plugin>
