cannot use resource wildcards for the same classpath in multiple JARs #593

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Create 2 JARs with resources at the same path - i.e. assets/css/
2. Create an application with wro4j that includes the JARs, and configure a 
group with a wildcard for the identical path - i.e. 
<css>classpath:assets/css/**.css</css>
3. Retrieve the group's generated CSS

What is the expected output? What do you see instead?

Expect to see the CSS from both JARs in the output, instead only see the CSS 
from the first JAR matched.

What version of the product are you using? On what operating system?

v1.5.0
OSX

Here is a quick workaround for issue. Its very hacky, but works.
I hope you will find a way to properly implement it in core.

The root problem to implement it properly is the fact that api always work with 
single file/jar.
In our case the problem is here:
WildcardStreamLocator#InputStream locateStream(final String uri, final File 
folder)

Also, group resource may be expanded only once, and cant work in "apend" way.

MultiJarClasspathUriLocator is almost a copy of ClasspathUriLocator, but it use
getClass().getClassLoader().getResources(fullPath); 
to resolve all affected jars. 
It supplies MultiFile instead of simple File into stream locator, which simply 
holds few files instead of one.
Also, default JarWildcardStreamLocator is substituted with 
MultiJarWildcardStreamLocator, which can work with multiply jars (knows about 
MultiFile).

This code may be used without library modification, just compile and add to 
classpath. New locator will be registered under classpath2 alias. To make it 
work just set it in priority with property:
uriLocators=servletContext,uri,classpath2

Thank you very much. I'll take a look to your implementation and hopefully will 
add it to the core for next release.
