When using the shaded artifact in a project with no other dependencies, the code generator says:

An example project here reproduces it:

https://github.com/io7m/adt4j_test

[sviperll]

It's seems that you additionally need com.google.code.findbugs:annotations package

        <dependency>
            <groupId>com.google.code.findbugs</groupId>
            <artifactId>annotations</artifactId>
            <version>2.0.3</version> <!-- Any version should work -->
        </dependency>

We may need to add an option not to use additional annotations... You can add missing dependency as a workaround for now.

[io7m]

Do the annotations appear in the generated code? If so, it might be preferable to add an option to specify which @Nonnull class to use, as there are many competing standards.

[sviperll]

Yes, It's currently not configurable. There should be some kind of

    enum NonnullAnnotaionFlavour {
        NONE,
        FINDBUGS_ANNOTATIONS,
        CHECKERFRAMEWORK,
        // ...
    }

[io7m]

Would it be possible to simply specify a fully-qualified name of an annotation?

[sviperll]

I've released 3.0-rc1 version. javax.annotation.Nullable, javax.annotation.Nonnull and javax.annotation.ParametersAreNonnullByDefault are used only if these classes are present in classpath during compilation
