Generate Code from Thrift Definitions

Problem

You've created Thrift definitions (structs, services, etc.) and you need to generated either Thrift-based

• classes for use within your Scala or Java project, or
• libraries that can be used by your project or other projects.

Solution

Use the gen goal to generate code from Thrift definitions. Here's an example:

$ ./pants gen myproject/src/thrift:thrift-scala

If you need to compile a Scala or Java library target instead, use the compile goal instead.

Discussion

There are two types of Thrift target definitions that you will find in BUILD files in existing projects:

• java_thrift_library (for Scala and Java)
• python_thrift_library (for Python)

You can use the gen and compile goals directly with java_thrift_library targets. Thus, you could target a BUILD file containing this definition...

java_thrift_library(name='thrift-java',
  # Other parameters
)

...like this using Pants:

$ ./pants gen myproject/src/main/thrift:thrift-java
