This article mainly explains "how to build the fe development environment under apache doris windows". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to build a fe development environment under apache doris windows.

1. Environmental preparation

JDK1.8+, Intellj IDEA

The main purpose of compiling the fe front-end code on 1.linux is to obtain the automatically generated code and add it to the previous project to compile the fe project in idea.

Under linux, go to the source directory and execute the following command:

$sh build.sh-clean-fe

Then package the gensrc directory and take it out, as shown in the following figure

two。 Decompress gensrc.tar.gz under windows, and the decompressed directory is as follows:

3. Enter build/java and copy the whole part listed in red to the fe/src/main/java directory of the source code.

two。 Debug

1. Import fe Project with idea

two。 Create the directory marked in the red box below under the fe directory and copy the contents of the webroot into it

3. Configure conf/fe.conf

Here is my own configuration, which you can modify according to your own needs.
