在eclipse中导入外部jar

Question

I'm writing assignment on coursera.org Java course. I'm using Maven and I have external jars that I have to use in this course (course requirements).

This is part of my pom.xml:

<dependency>
  <groupId>org.coursera.algs4part1</groupId>
  <artifactId>stdlib</artifactId>
  <version>1.0</version>
</dependency>

I can't make java compiler import the external jar file. Below, following errors occur:

The import org.coursera.algs4part1.stdlib cannot be resolved

But I've successfully added the jar to maven:

What am I missing?

Answer 1

You need to do the following steps if you have a eclipse-maven plugin installed.

1. Run the command mvn eclipse:eclipse
2. Go to Project Properties > Build Path > Libraries tab > Add Variable... button > Configure Variables... button > New button. Enter the variable name as M2_REPO and its value/path to the Maven Repository path (Usually it's like C:\\Users\\<username>\\.m2\\repository .)

Answer 2

1.create a folder src\\lib and paste your jar file

2.your pom.xml should be like this.

 <groupId>org.coursera.algs4part1</groupId>
     <artifactId>stdlib</artifactId>
     <scope>system</scope>
     <version>1.0</version>
     <systemPath>${basedir}\src\lib\stdlib.jar</systemPath>
  </dependency>
