Setting Up dev env for FE - IntelliJ IDEA	en

Setting Up Development Environment for FE using IntelliJ IDEA

Prerequisites

• Git
• JDK1.8+
• IntelliJ IDEA
• Maven (Optional, IDEA shipped embedded Maven3)

Clone Code

Git clone codebase from https://github.com/apache/incubator-doris.git

Code Generation

If your are only interested in FE module, and for some reason you can't or don't want to compile full thirdparty libraries, the minimum tool required for FE module is thrift, so you can manually install thrift and copy or create a link of the executable thrift command to ./thirdparty/installed/bin.

Doris build against thrift 0.13.0 ( note : Doris 0.15 and later version build against thrift 0.13.0 , the previous version is still thrift 0.9.3)

If your are using macOS, try brew install thrift@0.13.0 and will get thrift 0.13.0 installed at /usr/local/opt/thrift@0.13.0/bin/thrift, then create a soft link to ./thirdparty/installed/bin/thrift.

For Windows users, download thrift 0.13.0 from http://archive.apache.org/dist/thrift/0.13.0/thrift-0.13.0.exe, and put it into thirdparty/installed/bin/ folder.

Go to ./fe folder and run the following maven command to generate sources.

mvn generate-sources

If fails, run following command first to try to install modules into maven local repository, then re-run above command.

mvn install -DskipTests

You can also use IDE embedded GUI tools to run maven command to generate sources

If you are developing on the OS which lack of support to run shell script and make such as Windows, a workround here is generate codes in Linux and copy them back. Using Docker should also be an option.

Import into IDEA

1. Import ./fe into IDEA

2. Follow the picture to create the folders

3. Build ui project , and copy files from directory ui/dist into directory webroot ( you can skip this step , if you don't need Doris UI )

Custom FE configuration

Copy below content into conf/fe.conf and tune it to fit your environment.
