How can I debug in eclipse with this plugin?

[Zhxhh]

I have done as follows:

1. Clone the repo
2. Import the repo into Eclipse with GhidraDev plugin installed
3. Link Ghidra to your Ghidra's installation (option in the project's context menu)
   Then I click "Run" in eclipse. Ghidra started then I drag "samples/ndoejs_x86/raw_x86.jsc" in it.
   However, it can't automatically distinguish language so I select v8 bytecode_x32, then console's output is

ERROR Language V8:LE:32:default does not specify a valid pcodeInjectLibraryClass (BasicCompilerSpec)  
ERROR Error Importing File: Error importing file: raw_x86.jsc (ImporterUtilities) java.lang.RuntimeException: Failed to instantiate v8_bytecode.V8_PcodeInjectLibrary for language V8:LE:32:default
