# JAVA BINDINGS FOR THRIFT ENDPOINT
#
# There are two JAR files that we expect Java clients to use:
# 1. A JAR that defines Eden's Thrift API.
# 2. A JAR that contains the general Java library for Thrift.
#
# For 1, when eden.thrift changes:
#
#     buck build \
#         --config java.target_level=7 \
#         --config java.source_level=7 \
#        //eden/fs/service:thrift-java
#
# Copy the resulting JAR
# (`buck targets --show-output //eden/fs/service:thrift-java`) to the project
# where you are using Eden in Java. (Note that the Java 7 config options are
# specified because Buck itself is currently limited to Java 7.)
#
# For 2, you should only have to build this once:
#
#     buck build \
#         --config java.target_level=7 \
#         --config java.source_level=7 \
#        //eden/fs/service:java-thrift-dependencies
#
# Copy the resulting JAR
# (`buck targets --show-output //eden/fs/service:java-thrift-dependencies`) to
# any project where you are using Thrift in Java. In theory, if the Java
# bindings for Thrift change, you will have to rebuild this, but it's unclear
# whether that code sees much activity these days. To be safe, you could always
# update this JAR when you update the Eden JAR.

# This java_binary() exists as a simple way to get //thrift/lib/java/src:thrift
# and all of its transitive dependencies into one JAR file.
#
# TODO: This is disabled in the open source build for now just because we
# don't have java build rules working yet.  We should re-enable it once
# we get java+thrift working in the open source build.
