Maven: mvn compile failure. "package does not exist". Dependency included in maven, Other SO Solutions Not Working. What am I missing?

I know that there are a lot of other SO answers on this topic, and although this question seems to have been the most useful, none of those solutions have led me to a complete resolution of my problem. So I could use a bit more help.

I have a Netbeans project created by someone who worked at my company before me, that has never been built with Maven, and I have haven't fully dived into the source of the project yet. However, because the number of dependencies for the project seemed overwhelming to me, I decided that I needed to figure out a management solution. This led me to Maven, and then indirectly to Apache Archiva.

So I set up an Archiva repository and uploaded all of the dependencies needed by the project. All of these artifacts are JAR files. I then created a pom.xml file in the preexisting project directory and tweaked the build settings to match the project. Now the project directory looks like this:

ProjectStructure and Import Error In Source Code

In the above screenshot, you can also see the error on line 12. This error says "package.imgscalr does not exist" this is later echoed by mvn compile.

The full project POM looks like this:

So, the obvious problem is that maven can't seem to find the org.imgscalr package. But, none of my dependencies were overwritten or removed--based on the dependency tree produced by mvn dependency:tree -Dverbose, including the imgscalr-lib dependency (This is a JAR which contains the org.imgscalr package and META-INF).

Suspecting corruption, I deleted the imgscaler-lib folder in the local repository--and then the entire repository--neither of these worked. Upon compiling, Maven reacquired all of the files from my Archiva repository, but the problem persists.

I have checked mvn help:effective-pom, and it seems to match my pom.xml.

I have also tried running mvn dependency:copy-dependencies as suggested in the linked question, and all of my libraries are successfully copied into the target directory, including the library in question: org.imgscalr

What am I missing here?

edit: Updated pom.xml to add repository information

edit: The reason I have very weird version numbers in my pom.xml is because I uploaded artifacts to Archiva from a folder given to me by my predecessor. A lot of loose artifacts didn't have any version numbers, so I labeled these unknown version numbers "0.0"

edit: Deleted repository again after adding repo information to pom.xml. Ran another clean goal and another compile goal. Maven reacquired dependencies. I have confirmed that maven is getting the artifact from my Archiva Repository. Problem persists.

From a comment:

The package is DEFINITELY in the .jar. Not a .class file, but 3 .java source files. Including one called Scalr.java which appears to be the one that the compiler is complaining about.

This is your problem. Jars should contain compiled .class files, not source files, such as *.java files. You have put source jars in Archiva, but they're meant to be jars that contain compiled files.

I'm guessing you got those .jars through some unorthodox way, not by using regular tools.
