-------------------------------------

[~coldmoon7777777] Hi, thanks for reporting the problem!

The flink/target folder can not be used as the FLINK_HOME. However, you can set FLINK_HOME to flink/flink-dist/target/flink-${project.version}-bin/flink-${project.version} if flink/build-target is not generated when build under windows. 

The flink/build-target is generated only under Unix systems as a symbolic link of the flink/flink-dist/target/flink-${project.version}-bin/flink-${project.version} folder.

>             Project: Flink
>          Issue Type: Bug
>          Components: API / Python, Build System
>    Affects Versions: 1.9.0, 1.10.0
>         Environment: windows 10 enterprise x64（mentioned as build environment, not development environment.）
> powershell x64
> flink source master and 1.9.0 version
> jdk-8u202
> maven-3.2.5
>            Reporter: Xu Yang
>            Priority: Blocker
>              Labels: beginner, build
>         Attachments: setup.py
>
>   Original Estimate: 1h
>  Remaining Estimate: 1h
>
> ATTENTION: This is a issue about building pyflink, not development.
> During we build pyflink...
> After we have built flink from flink source code, a folder named "target" is generated.
> Then, following the document description, "cd flink-python; python3 setup.py sdist bdist_wheel", error happens.
> Root cause: in the setup.py file, line 75, "FLINK_HOME = os.path.abspath("../build-target")", the program can't found folder "build-target", however, the building of flink generated a folder named "target". So error happens in this way...
>  
> The right way:
> in ../flink-python/setup.py line 75, modify code as following:
> FLINK_HOME = os.path.abspath("../target")
