The code imports classes from a compiled jar file. It can't access these
classes even though I've installed the jar file in my local repository,
listed it as a dependency in my pom.xml file, and it compiles happily. I've
tried changing plugins and configuration based on advice in the archive, but
it has only changed my error.
Details
----------
I have some java code that is dependent on classes contained within a
pre-compiled, third-party proprietary jar file called aipartner_api.jar. I
have installed this jar in my local repository thusly:
mvn install:install-file -Dfile=. \
-DgroupId=com.adinfuse.api \
-DartifactId=aipartner_api.jar \
-Dversion=1.0 \
-Dpackaging=jar \
-DgeneratePom=true
so a copy lives here:
YPCMC10030:target lbickle$ ls
/Users/lbickle/.m2/repository/com/adinfuse/api/aipartner_api/1.0/
aipartner_api-1.0.jar aipartner_api-1.0.pom
mvn clean package executes happily:

When I used the maven-jar-plugin, I got an error, but, I read the
archive and someone with a similar problem was pointed to this post:
http://thomassundberg.wordpress.com/2011/03/05/create-an-executable-jar-from-maven/
Here's the error:
YPCMC10030:target lbickle$ java -jar reportingapi.jar
Exception in thread "main" java.lang.NoClassDefFoundError:
com/adinfuse/api/Reporting
Caused by: java.lang.ClassNotFoundException: com.adinfuse.api.Reporting

So, I changed my pom.xml to this:
<?xml version="1.0" encoding="UTF-8"?>

And now I get error instead:
YPCMC10030:api lbickle$ java -jar target/reportingapi.jar
Failed to load Main-Class manifest attribute from
target/reportingapi.jar
The imports look like this:
import com.adinfuse.api.*;
import com.adinfuse.api.cs.Advertisement;
import com.adinfuse.api.cs.ContentPlacement;
import com.adinfuse.api.cs.Creative;
import com.adinfuse.api.rpt.*;
import com.adinfuse.api.org.*;
The offending line is this:
Reporting rpt =
AdInfuseAPI.getReporting("intouch.adinfuse.com");
The Reporting class is in com.adinfuse.api.
I've tried googling "maven java jar java.lang.ClassNotFoundError",
"maven java jar java.lang.NoClassDefFoundError" and "maven import
dependency"
I've also tried searching the mailing list archives, but I don't see
anything it suggests to do that I haven't already done.
Any help is appreciated!
