为什么mvn install没有为已安装的jar提供依赖项?

我习惯于构建一个我需要在本地仓库中安装的库,以便在其他项目中使用。

我已在项目mvn install中尝试basedir

我已经尝试maven-install-plugin

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-install-plugin</artifactId>
    <version>2.3.1</version>
    <configuration>
      <groupId>somegroup</groupId>
      <artifactId>someartifact</artifactId>
      <version>1.0</version>
      <packaging>jar</packaging>
      <file>${basedir}/target/someartifact.jar</file>
      <generatePom>true</generatePom>
    </configuration>
    <executions>
      <execution>
        <id>install-jar-lib</id>
        <goals>
          <goal>install-file</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

正确安装了jar,但是当我添加依赖

<dependency>
  <groupId>somegroup</groupId>
  <artifactId>someartifact</artifactId>
  <version>1.0</version>
</dependency>

列出的其他项目未显示过渡依赖项。

当运行项目测试失败且NoClassDefFoundError转换依赖项时,会出现问题。

如何解决这个问题?

install-file目标是将外部jar文件安装到本地存储库中。它并不意味着用于安装由Maven构建的项目生成的工件。应该使用maven-install-plugin的install目标安装此类项目。此目标会自动安装项目的pom(定义依赖项)以及存储库中的工件。

它还有一个优点,就是不需要在pom中配置install-plugin。它始终是构建的一部分。只需在你的pom中没有配置maven-install-plugin就可以调用mvn install
