Add resources, config files to your jar using grad

问题:

How do I add config files or any other resources into my jar using gradle?

My project structure:

src/main/java/com/perseus/.. --- Java packages (source files)

src/main/java/config/*.xml --- Spring config files

Expected jar structure:

com/perseus/.. --- Java packages (class files)

config/*.xml --- Spring config files

回答1:

Move the config files from src/main/java to src/main/resources.

Thanks guys, I was migrating an existing project to Gradle and didn't like the idea of changing the project structure that much.

I have figured it out, thought this information could be useful to beginners.

Here is a sample task from my 'build.gradle':

version = '1.0.0'

jar {
   baseName = 'analytics'
   from('src/main/java') {
      include 'config/**/*.xml'
   }

   manifest {
       attributes 'Implementation-Title': 'Analytics Library', 'Implementation-Version': version
   }
}

I came across this post searching how to add an extra directory for resources. I found a solution that may be useful to someone. Here is my final configuration to get that:

sourceSets {
    main {
        resources {
            srcDirs "src/main/resources", "src/main/configs"
        }
    }
}

回答4:

By default any files you add to src/main/resources will be included in the jar.

If you need to change that behavior for whatever reason, you can do so by configuring sourceSets.

This part of the documentation has all the details

I ran into the same problem. I had a PNG file in a Java package and it wasn't exported in the final JAR along with the sources, which caused the app to crash upon start (file not found).

None of the answers above solved my problem but I found the solution on the Gradle forums. I added the following to my build.gradle file :

sourceSets.main.resources.srcDirs = [ "src/" ]
sourceSets.main.resources.includes = [ "**/*.png" ]

It tells Gradle to look for resources in the src folder, and ask it to include only PNG files.

EDIT: Beware that if you're using Eclipse, this will break your run configurations and you'll get a main class not found error when trying to run your program. To fix that, the only solution I've found is to move the image(s) to another directory, res/ for example, and to set it as srcDirs instead of src/.
