Building the old custom snap

[Harriesh]

I was not able to build the old custom snap , So I used the latest POM from demosnap and build the custom snap .

Now the build ran successfully . But all tests are failing with the same reason .

And I can see logs , the schemas are generated but in the different location,

I used both GitHub - SnapLogic/DemoSnapPack: A Snap Pack for demonstration and references purposes. This is the ... and Maven project generated from archetype. I am getting the same error during unit tests: Unable to get schema: com-snaplogic-snap-template_2, FileNotFoundException: .\jschema\src\test\resources\schema\com-snaplogic-snap-template_2.schema. There is no com-snaplogic-snap-template_2.schema in git project at this location, not in project generated from archetype. I use maven 3.5, since issue ARCHETYPE-519 in Snap Development Documentation was fixed, we do not have to use maven 2.4.

Just build your project without the tests. Something is changed I believe in the code or in the tests, that is why they are not completing properly. When you pack the snap pack just use:

mvn clean install -D skipTests=true

This will skip the tests.
