A Gradle plugin to import and repackage dependencies Proguard tool.

Apply the plugin:

plugins {
    java
    id("io.github.gmazzo.importclasses") version "<latest>"
}

importClasses {
    dependencies("org.apache.commons:commons-lang3:3.14.0")
    repackageTo = "org.test.imported"
    keep("org.apache.commons.lang3.StringUtils")
}

You can also use importClasses and importClassesLibrary configurations in the project's dependencies block:.

dependencies {
    importClasses("org.apache.commons:commons-lang3:3.14.0")
}

The companion importClassesLibrary will be mapped to Proguard's -libraryjars option.

Then the SourceSet will have the class org.apache.commons.lang3.StringUtils from ( org.apache.commons:commons-lang3:3.14.0) imported and repackaged as org.test.imported.StringUtils.

package org.test;

import org.test.imported.StringUtils;

public class Foo {

    public String swapCase(String string) {
        return StringUtils.swapCase(string);
    }

}

By default, the plugin will bind with the main SourceSet, and works with java and android plugins. Further specific imports can be done by creating new specs matching a Java SourceSet or an Android Variant name

You can configure multiple (and isolated) importClasses through the DSL:

importClasses {
    specs {
        create("debug") {  // will be imported onto Android's `debug` source set only
            dependencies("org.foo:foo:1.0.0")
            repackageTo = "org.foo.another.imported"
            keep("org.foo.AnotherClass")
        }
    }
}
