Maven failing to find jar from Project Repository

Issue

I have a jar file which I need to include in my project. I am using eclipse with Maven

I created the following folder in my project on my computer:

/home/robert/eclipse/BobProjects/BobDiary/in_project_maven_repository/metcarob.com.lib/nachocalendar/0.23

and I placed a file there called:

nachocalendar-0.23.jar

I then added the dependancy to my POM file:

<dependency>
  <groupId>metcarob.com.lib</groupId>
  <artifactId>nachocalendar</artifactId>
  <version>0.23</version>
  <scope>compile</scope>
</dependency>

I also added the Repo into my pom file:

    <repository>
      <id>in-project</id>
      <name>In Project Repo</name>
      <url>file:///home/robert/eclipse/BobProjects/BobDiary/in_project_maven_repository</url>
    </repository>

from what I understand this should work. When I right click on my project select run as and maven install I get the following error:

[ERROR] Failed to execute goal on project BobDiary: Could not resolve dependencies for project metcarob.com.BobDiary:BobDiary:jar:0.0.1-SNAPSHOT: Failure to find metcarob.com.lib:nachocalendar:jar:0.23 in file:///home/robert/eclipse/BobProjects/BobDiary/in_project_maven_repository was cached in the local repository, resolution will not be reattempted until the update interval of in-project has elapsed or updates are forced -> [Help 1]
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal on project BobDiary: Could not resolve dependencies for project metcarob.com.BobDiary:BobDiary:jar:0.0.1-SNAPSHOT: Failure to find metcarob.com.lib:nachocalendar:jar:0.23 in file:///home/robert/eclipse/BobProjects/BobDiary/

I have followed all the steps I can see for creating an in project repository but it still seems to not be able to find the file.

Does anyone know of a step I am missing?

Thanks Robert

Update: I must have made mutiple mistakes. Akber found my first mistake: I have changed the folder so the group ID is in seperate folders: (metcarob.com.lib is now metcarob.com.lib) The jar file is now in: /home/robert/eclipse/BobProjects/BobDiary/in_project_maven_repository/metcarob/com/lib/nachocalendar/0.23

I have verified this because the following directory exists in my machine: ~/.m2/repository/metcarob/com/lib/nachocalendar/0.23

I have moved the file, restarted eclipse and re-ran maven clean and maven install.

The error is now:

[ERROR] Failed to execute goal on project BobDiary: Could not resolve dependencies for project metcarob.com.BobDiary:BobDiary:jar:0.0.1-SNAPSHOT: Failure to find metcarob.com.lib:nachocalendar:jar:0.23 in file:///home/robert/eclipse/BobProjects/BobDiary/in_project_maven_repository was cached in the local repository, resolution will not be reattempted until the update interval of in-project has elapsed or updates are forced -> [Help 1]

However I also put this project into gitlab and use CI to compile it there with the command mvn install -B My project now finds the dependency and compiles on the gitlab CI server.

Solution

Most likely, one of two problems:

1. Each part of the group id needs to be its own folder.
2. The pom.xml of the dependency should exist int the same folder in the repo.
