Can't find sources for python-ce.jar when developing a plugin

Please show your build.gradle definition. Did you follow guide from https://plugins.jetbrains.com/docs/intellij/pycharm.html?

build.gradle

intellij {
    version '2020.2.3'
    type "PC"
    updateSinceUntilBuild false
    downloadSources true
    plugins "python-ce"
}

plugin.xml

<depends>com.intellij.modules.lang</depends>
<depends>com.intellij.modules.python</depends>
<depends>com.intellij.modules.platform</depends>

The plugin is building fine thought, I just can't access the SDK sources/docs.

Just a little question: is the python-ce API closed source? Because even searching on the net I couldn't find any docs/sources about it. If so then it would be pretty difficult to use the API, and maybe I legally shouldn't. And considering it true, is it the same for the remaining languages (except Java which I already tried with success)?.

Python Community Edition is OSS, the sources are part of IntelliJ Community.

Please try removing this line from your build.gradle

> plugins "python-ce"

I tried, now all the python SDK isn't loaded/recognized.

And this dependency in the plugin.xml becomes invalid.

If you want I can submit a minimal repo.

I tried testing this project: https://github.com/JetBrains/intellij-sdk-code-samples/tree/main/product_specific

It builds fine but with no Python Psi support, which means for example PyClass/PyFile etc... aren't defined.

Adding:

intellij {
    ....
    plugins "python-ce"
}

gives access to PyClass/PyFile etc... but with no sources docs, like this for instance:

As you see it is pretty much unclear what is what, and clicking on Download Sources... fails

Is it related to this?

https://plugins.jetbrains.com/docs/intellij/pycharm.html#configuring-plugin-projects-targeting-pycharm 

Because what I can understand from this is that I can't access sources of the sdk because they are non public.

Can you give me a link where I can find the repo of python-ce.jar? Because I couldn't find anything on google/github

Thanks again.

After some efforts, finally I found the repo: https://github.com/JetBrains/intellij-community/tree/master/python/

Now should I clone it and point to it with Choose Souces... (what about version conflicts!) or is there any easier method around?

Hello, indeed there are currently no source artifacts provided when targeting PyCharm explicitly. A workaround would be to target IC (IntelliJ Community Edition) and require matching Python plugin (https://plugins.jetbrains.com/plugin/631-python/versions) instead (see https://github.com/jansorg/pycharm-flake8/blob/master/build.gradle as sample)

Please watch https://youtrack.jetbrains.com/issue/PY-49166

Hi Yann Cebron, unfortunately, the link you provided is broken. Is there any update on the situation?

It's quite frustrating to not be able to see the source code when developing new plugins for PyCharm.

Mentioned ticket is indeed internal; however, the latest update is:

Sources are provided for PyCharm plugin development since gradle-intellij-plugin 1.1.0, next step is to provide sources for IDEA + Python plugin development.

Why do you need to specify the version number instead of automatically matching the version number of intellij version。If no version number is specified， it report cannot find builtin plugin PythonCore
