R8 integration issue when building release with gradle in android application

[courville]

Hi,

I am trying to switch to opensub4j in my Nova Video Player android application and when adding in dependenciesimplementation 'com.github.wtekiela:opensub4j:0.2.3' I cannot build anymore my application and R8 throws the following error:

.gradle/caches/modules-2/files-2.1/junit/junit/3.8.1/99129f16442844f6a4a11ae22fbbee40b14d774f/junit-3.8.1.jar: R8: Illegal invoke-super to void java.awt.Component.setBounds(int, int, int, int) from class junit.awtui.ProgressBar

Would you have any workaround or recommendation?

Thank you for your work and contribution.

Hi, it looks like your error comes from junit-3.8.1.jar.

My library does not depend on it directly, but It seems like it is transitively included:

\--- org.apache.xmlrpc:xmlrpc-client:3.1.3
     \--- org.apache.xmlrpc:xmlrpc-common:3.1.3
          \--- org.apache.ws.commons.util:ws-commons-util:1.0.2
               +--- junit:junit:3.8.1
               \--- xml-apis:xml-apis:1.0.b2

For the time being, you need to exclude junit transitive dependency in your project, e.g. like this:

    compile('com.github.wtekiela:opensub4j:0.2.3') {
        exclude group: 'junit', module: 'junit'
    }

Will fix in 0.2.4.

Thanks for the quick feedback, it works with your proposed fix. Will pick up 0.2.4 when available.
