[DOCUMENT] Fix duplicate class errors If a class appears more than once on the runtime classpath, you get an error similar to the following: Program type already present com.example.MyClass This error typically occurs due to one of the following circumstances: A binary dependency includes a library that your app also includes as a direct dependency. For example, your app declares a direct dependency on Library A and Library B, but Library A already includes Library B in its binary. To resolve this issue, remove Library B as a direct dependency. Your app has a local binary dependency and a remote binary dependency on the same library. To resolve this issue, remove one of the binary dependencies. [DOCUMENT END]
