I'm using the Eclipse Java IDE with the Maven plugin and artifactory as
the repository. I have configured the POM to use the
maven-assembly-plugin to create an executable jar (see below).
When packaging I get the error 'Unable to obtain unarchiver for
file...'. This only occurs when I have multiple projects open in the
same workspace of Eclipse, with dependencies between each other. I.e. if
I have two project open 'A' and 'B' and B depends on the jar of A, then
if I have both open in the workspace the build of B will fail. However
if I upload the A jar to artifactory, delete the project from the
workspace and build, then maven download the jar correctly and packages
B without any problem.
Ideas?
