在Maven本地存储库中安装的外部jar上无法解析类导入

Question

I am using maven 3.2.5. I have one external jars which I need to use in my maven project which is not available in maven repository.

I installed those jars by using following command:

1) mvn install:install-file -Dfile=p-unit-0.15.319.jar -DgroupId=org.punit -DartifactId=p-unit -Dversion=0.15.319 -Dpackaging=jar

2) After this command, I saw in my M2 repository, jar & pom was created .m2\\repository\\org\\punit\\p-unit\\0.15.319\\p-unit-0.15.319.jar .m2\\repository\\org\\punit\\p-unit\\0.15.319\\p-unit-0.15.319.pom

created pom content:

<?xml version="1.0" encoding="UTF-8"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>
  <groupId>org.punit</groupId>
  <artifactId>p-unit</artifactId>
  <version>0.15.319</version>
  <description>POM was created from install:install-file</description>
</project>

3) Updated the pom file

<dependency>
  <groupId>org.punit</groupId>
  <artifactId>p-unit</artifactId>
  <version>0.15.319</version>   
  <scope>provided</scope>                                         
</dependency>

Issue: When I tried to use class of this jar,

 import org.punit.runner.*;
 getting error: import org.punit.runner can't be resolved.

I tried many combination to define the dependency but not able to use the classes.

How can I resolve it??

Answer 1

Add the corresponding dependency to the pom.xml file of your project under the tag dependencies.

Example :

<dependencies>
    <dependency>
      <groupId>org.punit</groupId>
      <artifactId>p-unit</artifactId>
      <version>0.15.319</version>   
      <scope>test</scope>
    </dependency>
</dependencies>

Note : assuming the group,artifact ids and version are correct as mentioned in the question.

Answer 2

One thing which I missed, I am mentioning here, which solved this issue. I had put the dependency in wrong profile which was not called during my compilation. When I put in correct profile it worked.

Second option:

We can directly add external jar through eclipse:

Properties -> Java Build Path -> Libraries -> Add External Jars.

and locate the library on the file system.
