Gradle, how to exclude a class/package from dependency jar file?

Question

I have Findbugs plugin in my main build.gradle file. In order to stop its complain regard some issues I have added annotation.jar and jsr305.jar into my libs folder and I'm using @SuppressFBWarnings wherever needed.

I'm getting following error when I try to build my project.:passenger-

app:dexTaxDebug
UNEXPECTED TOP-LEVEL EXCEPTION:

Note: I know a solution is activating multidex Building Apps with Over 65K Methods. I also don't believe Progard :(

So, I'm looking for a way to exclude a class from dependent jar file if it's possible. We have something for modules for seems is not possile for jar file.

compile('com.google.android.gms:play-services-analytics:7.3.0') {
        exclude group: 'com.google.android.gms', module: 'play-services-base'
    }

What I have in my main build.gradle file

configure(allprojects) {
    apply plugin: 'findbugs'

    task findbugs(type: FindBugs) {
        ignoreFailures = false
        effort = "max"

        classes = fileTree('build/intermediates/classes/')
        source = fileTree('src/main/java')
        classpath = files()

        excludeFilter = file("$rootProject.rootDir/config/findbugs/exclude.xml")

        reportLevel = "high"
        reports {
            xml.enabled = false
            html.enabled = true
        }
    }
}

and these dependencies in my dependency project

dependencies {
    ....

    // Findbugs libs in order to surpass warnings
    compile files('src/main/libs/annotations.jar')
    compile files('src/main/libs/jsr305.jar')

    ....
}

any suggestion would be appreciated.

This should allow you to not include individual packages from your jar.sourceSets { main { java { include 'com/ourcompany/somepackage/activityadapter/**' include 'com/ourcompany/someotherpackage/**' exclude 'com/ourcompany/someotherpackage/polling/**' } } } original SO post here http://stackoverflow.com/questions/27965690/gradle-exclude-or-add-reference-for-jar-file-hard-included-inside-library-class — Doug Ray, Oct 28 '15 at 20:30
@DougRay Thanks man. Yup, I saw that suggestion and we are using it for some other classes. But that prevents our class get included to jar file. The thing I'm looking for is I have jar and I want to tell buid system that don't include a class. I'm actually not sure my idea works :( — Hesam, Oct 28 '15 at 21:02
hmmm ok well the next best step would probably be to pick through the gradle documentation. Probablly around the java closures https://docs.gradle.org/current/userguide/java_plugin.html. — Doug Ray, Oct 29 '15 at 00:55

Try modifiying the jar closure like this example maybe

project(':api:core') {

        dependencies {
                compile project(':api:schema')
                compile project(':api:util')
        }

        jar {
                baseName = 'core'
                dependsOn classes
                from sourceSets.main.classes
                exclude('net/intellidata/core/**/*Impl*')
        }

        task caaJar(type: Jar) {
                baseName = 'caa' 
                dependsOn classes 
                from sourceSets.main.classes
                include('net/intellidata/core/**/CAA*Impl*')
        }
}

not clear how the above helps. OP asked how to exclude dependencies that are brought in by, for example, jsr305.jar — V P, Jul 31 '20 at 14:07
