R.txt isn't a file error when building aar

[Mustafa Sezgin]

Hey all,

Im currently having an issue on the 3.8.2 version of the plugin. Im trying to build an aar library with shared libraries that have been built with the ndk. The build fails with the following error

Maven version is 3.1.1. Even if I make the pom very simple as follows

<plugin>
                <groupId>com.jayway.maven.plugins.android.generation2</groupId>
                <artifactId>android-maven-plugin</artifactId>
                <version>3.8.2</version>
                <configuration>
                    <sdk>
                        <platform>${androidApiLevel}</platform>
                    </sdk>
                </configuration>
                <extensions>true</extensions>
            </plugin>

It still produces the same error. Been trying a lot of things but cannot get past this. Any help would be appreciated.

Try the 3.8.3-SNAPSHOT version..  3.8.,2 is very different and has various problems that we are addressing currently.
