With this change all resources within function's src/main/resources will be added to function.jar.
Before that they used to be omited.
The distribution, created after gradle build was modifying the jars, excluding all resoursed.
Fixed that by deleting this distribution and creating a controlled one with gradle distZip

Motivation and Context

  • I have raised an issue to propose this change (required)

Which issue(s) this PR fixes

Fixes #72

How Has This Been Tested?

$ faas-cli build
$ docker run -ti hello-java sh
$ cd entry point-1.0/libs
$ jar xf function-1.0.jar
$ ls

META-INF      function-1.0.jar      com       res_file.xml

Tested function from @spacedoudou with updated template:
https://github.com/spacedoudou/openfaas1

Fixed code in Handler.java to prefix resource file with /:

URL u = getClass().getResource("/res_file.xml");

$ echo "" | faas invoke hello-java
getResource = jar:file:/home/app/entrypoint-1.0/lib/function-1.0.jar!/res_file.xml

After modifying code to read contents:

$ curl -X GET http://127.0.0.1:8080/function/hello-java -d ""
getRessource = jar:file:/home/app/entrypoint-1.0/lib/function-1.0.jar!/res_file.xml

What is the impact on the build time before/after?

@ivanayov Is this still applicable? I am unable to duplicate the issue with the java8 template pulled as of this morning (21 Feb 2019). I followed your test procedure and was able to find the resource and load the content of the file without the changes suggested in this PR.

@tessellator When I run the current template, it does not find resources, I wrote functions to lists all files etc and it never found them

Hmm, that is really weird. Here are the changes I made to the sample function to list the file contents, and I get the following output:

➜  echo "" | faas invoke hello-java
getRessource = jar:file:/home/app/entrypoint-1.0/lib/function-1.0.jar!/res_file.xml
file content
end of file.%

Would you mind trying my version of the function and seeing what you get (repo link)? I just want to establish some common ground for debugging purposes.

Im not able to reproduce this using the latest templates. Resources are included in the built jar-file.
