安装第三方JAR

Question

I have a maven project in Eclipse called TdkUtils, with this pom.xml: This is a utils project. So I want to create a jar, put it in the repository and use it in another projects.

...
<groupId>com.tdk</groupId>
  <artifactId>tdkUtils</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>jar</packaging>

  <name>tdkUtils</name>
...

But I got these errors when installing the plugin:

MacBook-Pro-de-nunito:tdkUtils nunito$ mvn install:install-file -Dfile=target/tdkUtils-0.0.1-SNAPSHOT.jar

Answer 1

If you just execute mvn install while inside the same directory with the util pom.xml file, maven will install the jar file into local repository for the user.

After that, the jar file can be used by the same user from other projects.

Answer 2

您可以像这样不使用pom.xml将jar安装到本地存储库： mvn install:install-file -Dfile=target/tdkUtils-0.0.1-SNAPSHOT.jar -DgroupId=com.tdk -DartifactId=tdkUtils -Dversion=0.0.1-SNAPSHOT -Dpackaging=jar
