I googled this and it seems that no one has an answer, yet it seems like such an elementary thing that it should be possible.
I have the following project structure:
parent
---sub-project1
---sub-project2
sub-project2 needs to have sub-project1 as a dependency.
So I have this in sub-project2's pom:
<dependencies>
<dependency>
<artifactId>sub-project1</artifactId>
<groupId>mygroup</groupId>
<version>1.0-SNAPSHOT</version>
</dependency>
....
When I do this, Maven tries to dowload the sub-project1.jar file, which does not exist because it's not ready for the repo yet.
I tried to put a <scope>import</scope>
in the dependency, but that didn't work either -- same result.
So what do I have to do to get Maven to look at sub-project1 when building sub-project2?
EDIT Here are some pom snippets:
Parent:
<project
xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

....
sub-project1:

....
<dependency>
<artifactId>sub-project2</artifactId>

<version>1.0-SNAPSHOT</version>
<scope>import</scope>
</dependency>
</dependencies>
The error I'm getting when I got mvn clean install
on the parent is:
[ERROR] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
[INFO] Compilation failure
With a lot of classes/package not found errors
It should be enough to create a single POM to add all of the JARs providing you have a execution block for each jar you want to add. You just need to make sure that each block has a unique id. The result is a single Maven module that will add all the JARs into the local repo.
Add a Java Maven Dependency to the Utility Project field (e.g., commons-logging) to search for a dependency. Select the dependency, and click OK. Expand the utility project, right-click the pom. xml file, and select Run As>Maven Install to install the file into the local repository.
Multiple transitive dependencies can be excluded by using the <exclusion> tag for each of the dependency you want to exclude and placing all these exclusion tags inside the <exclusions> tag in pom. xml. You will need to mention the group id and artifact id of the dependency you wish to exclude in the exclusion tag.
You should have a master pom at parent's level, in which you will list the modules of your project.
<modules>
<module>sub-project1</module>
<module>sub-project2</module>>
</modules>
In each subproject you have to reference your parent:
<parent>
<artifactId>parent</artifactId>
<groupId>mygroup</groupId>
<version>1.0-SNAPSHOT</version>
</parent>
And you specify the dependencies between the project just as you did. I think you've missed some of the steps I've described.
Edit: you should issue your mvn clean install at the parent level.
