Java - 在 pom.xml 中添加 jar 依赖

Question

I have never built my java applications by maven. But when i am trying to do that it's giving me error. I have created JAR file from other java application just by exporting as JAR from that application. Now i want to add this JAR in my maven application. I don't really how to do that.

this is how i have added in pom.xml. But i don't really know what should be it's artifact id. Seriously what is artifact id?

<dependency>
        <groupId>ProjectZen</groupId>
        <artifactId>community</artifactId>
        <scope>system</scope>
        <version>1</version>
        <systemPath>${basedir}\libs\ProjectZen.jar</systemPath>
    </dependency>

I am getting below error

Missing artifact ProjectZen:community:jar:1

Answer 1

If it is custom jar you need to do following things Open cmd and type following command

  mvn install:install-file  -Dfile=path-to-your-artifact-jar \
                      -DgroupId=ProjectZen
                      -DartifactId=community
                      -Dversion=1
                      -Dpackaging=jar
                      -DgeneratePom=true

Now, the “ProjectZen” jar is copied to your Maven local repository.

In pom.xml

  <dependency>
    <groupId>ProjectZen</groupId>
    <artifactId>community</artifactId>
    <scope>system</scope>
    <version>1</version>
    <systemPath>${basedir}\libs\ProjectZen.jar</systemPath>
</dependency>

now the “ProjectZen” jar is able to retrieve from your Maven local repository.

Answer 2

change

<systemPath>${basedir}\libs\ProjectZen.jar</systemPath>

to

<systemPath>${basedir}/libs/ProjectZen.jar</systemPath>

or install it in local maven cache

Answer 3

you should give the format as below. and the slashes used in are incorrect I suppose. Check the dependency in this format. ...

<profiles>
<profile>
  <id>default-tools.jar</id>
  <activation>
    <property>
      <name>java.vendor</name>
      <value>Sun Microsystems Inc.</value>
    </property>
  </activation>
  <dependencies>
    <dependency>
      <groupId>com.sun</groupId>
      <artifactId>tools</artifactId>
      <version>1.4.2</version>
      <scope>system</scope>
      <systemPath>${java.home}/../lib/tools.jar</systemPath>
    </dependency>
  </dependencies>
</profile>
