Tries to download sources from wrong version (and fails)

IntelliJ Platform
1

Hi,

This is a snippet from my gradle.properties file (2025.1 is the platform version).

# Supported build number ranges and IntelliJ Platform versions -> https://plugins.jetbrains.com/docs/intellij/build-number-ranges.html
pluginSinceBuild = 251

# IntelliJ Platform Properties -> https://plugins.jetbrains.com/docs/intellij/tools-gradle-intellij-plugin.html#configuration-intellij-extension
platformType = PY
platformVersion = 2025.1

Still, when clicking the “Download Sources” link, there is an error message indicating an attempt to download 243 sources.

Is something wrong on my end?

For me it’s broken since a long time. 2025 or 2026 IDEs, it downloads something, then the sources are never attached.
I’ve given up, and I now use a dedicated IDE solely for browsing the IJ community’s source code, which I’ve cloned from GitHub.
