Originally reported to jetbrains but the offending code comes from the Studio fork, which adds the following code:

boolean skipTasks;
try {
  skipTasks = Boolean.parseBoolean(String.valueOf(project.getProperties().get("idea.gradle.do.not.build.tasks")).trim());
} catch (Throwable ignored) {
   skipTasks = false;
}

Original report to intellij copied below:

Steps to reproduce

Clone the reproducer project and checkout branch 2024.9
Attempt to sync the project in an IDE based on intellij 2024.2 (for example Android studio Ladybug canary09)
Sync will throw isolated projects errors from JetGradlePlugin

Expected result (correct result):

No isolated projects issues

Actual result (faulty result):

You will see thousands of the following isolated projects violation: Project ':whatever' cannot dynamically look up a property in the parent project ':' from com.intellij.gradle.toolingExtension.impl.model.taskIndex.GradleTaskIndexBuilder.buildAll(GradleTaskIndexBuilder.java:39)

Additionally, the project that this reproducer sample is based on also throws the same error from com.intellij.gradle.toolingExtension.impl.model.taskModel.GradleTaskModelBuilder.buildAll(GradleTaskModelBuilder.kt:31) but for some reason I haven't determined yet, this reproducer sample doesn't exhibit.

The stacktrace line numbers in the configuration cache report also does not line up with the code in the repo for the tag that this version of Studio is based on. Here's where I think the stacktrace points to, both of which are blank lines:

Neither class calls DefaultProject.getProperties as far as i can see in the source code in the links above.

Full stacktrace from the configuration cache report (which I can't attach because it is 105MB)
