在 pom.xml 依赖标签中添加 jar 文件的 systemPath

Question

I have imported an existing maven project into eclipse IDE. The pom.xml have a dependency looking like below.

    <dependency>
        <groupId>com.myApp</groupId>
        <artifactId>MyDBConn</artifactId>
        <version>0.0.0</version>
        <scope>system</scope>
        <systemPath>${basedir}/dependencies/MyDBConn.jar</systemPath>
    </dependency>

In the line

<systemPath>${basedir}/dependencies/MyDBConn.jar</systemPath>

I am getting an error saying

Multiple annotations found at this line: - 'dependencies.dependency.systemPath' for com.myApp:MyDBConn:jar should not point at files within the project directory, ${basedir}/dependencies/MultiDBConn.jar will be unresolvable by dependent projects - 'dependencies.dependency.systemPath' for com.myApp:MyDBConn:jar must specify an absolute path but is ${basedir}/dependencies/MyDBConn.jar

I have MyDBConn.jar file in dependencies folder inside the project directory. In my understanding ${basedir} points to the path where pom.xml is located. Why am i getting this error then?

Answer 1

That is not an error; it is a warning. Please check the logs again. Maven is warning you that the dependency MyDBConn.jar will not be available to other projects that depend on this project (the one that depends on MyDBConn.jar ).

Is com.myApp.MyDBConn something you wrote? You can run mvn clean install on that project to place the jar in your local Maven repository. Then, you can use it like:

<dependency>
    <groupId>com.myApp</groupId>
    <artifactId>MyDBConn</artifactId>
    <version>0.0.0</version>
</dependency>
