Maven cannot resolve dependency for project from source location

Question

I'm pretty new to maven so I am not sure how to fix this issue.

I am trying to package my maven project ( mvn clean package ) but I am getting this error:

Failed to execute goal on project TestSDK: Could not resolve dependencies for project com.company.idea.qe:qeTestSDK:jar:1.0-SNAPSHOT: Failure to find org.slf4j:slf4j-parent:jar:1.7.21 in http://nexus-proxy/nexus/content/groups/public/ was cached in the local repository, resolution will not be reattempted until the update interval of Company-nexus has elapsed or updates are forced -> [Help 1]

I believe this is caused by Maven using the repository value as the only source of downloading dependencies. I require this to download the WebDriverBuilder artifact. Being new to Maven I'm not sure how to do this.

my pom.xml currently looks like this:

http://maven.apache.org/xsd/maven-4.0.0.xsd"> 4.0.0

Answer 1

Your dependency should be for sl4j-api and not sl4j-parent

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.21</version>
</dependency>
