use protobuf3 with some lib which depends on protobuf2 in Java

Question

I'm using protobuf3 to represent our data, while we need hbase to store the data, it seems like hbase depends on protobuf2.

When i write the following line to create our hbase table

admin.createTable(desc);

then I got an Excepiton: NoClassDefFoundError: com/google/protobuf/LiteralByteString

I've tried using gradle's shadow plugin to relocate com.google.protobuf to shadow.google.com, then it throw a similar message NoClassDefFoundError: shadow/google/protobuf/LiteralByteString.

Create a sub-project, and name it 'hbase-wrapper'
Move the dependencies for hbase to the new project
Shadow protobuf in the new project
Add dependency to the sub-project on the main project

Here's some snip code

// part of build.gradle of the sub-project
...
dependencies {
    compile group: 'org.apache.hbase', name: 'hbase-client', version: '1.2.4'
}

shadowJar {
    relocate('com.google.protobuf', 'hbasesaver.google.protobuf')
}

// part of build.gradle for main project
...
compile project(path: ':hbase-wrapper', configuration: 'shadow')

use protobuf3 with some lib which depends on protobuf2 in Java
