The same set of types are supported. Details on how the binding works can be found [here](https://godoc.org/golang.org/x/mobile/cmd/gobind). ### Usage ``` gojava [-v] [-o ] [-s ] build [, [...]] This generates a jar containing Java bindings to the specified Go packages. -o string Path to write the generated jar file. (default "libgojava.jar") -s string Additional path to scan for Java source code. These files will be compiled and included in the final jar. -v Verbose output. ``` You can include the generated jar in your build using the build tool of your choice. The jar contains a native library (built for the build platform) which is loaded automatically. Cross platform builds are not currently supported. NOTE: This has only been tested on an OSX developer machine and Linux (on Travis) and not in production. ================================================ FILE: gojava.go ================================================ /* Command gojava is a tool for creating Java bindings to Go packages.
