The error message “cannot run project.afterevaluate(closure) when the project is already evaluated” typically occurs when you try to run a Gradle task that has already been evaluated and executed.
In Gradle, each task is evaluated once during the configuration phase and executed during the execution phase. Once a task is executed, it cannot be re-evaluated or executed again in the same Gradle run.
To resolve this issue, you can try the following approaches:
- Check if the task has already been executed: You can use the Gradle command-line interface (CLI) or the IDE’s Gradle tool window to determine if the task has already been executed. If it has, you may need to clean the project or run the task in a separate Gradle invocation.
- Use the Gradle incremental build: Gradle has built-in support for incremental builds, which avoids re-evaluating tasks that have already been executed. By enabling incremental build features for your project, Gradle will only re-evaluate the necessary tasks based on the changes made since the last build.
- Modify the task dependencies: If the error occurs due to the task dependencies, you can check and modify the task dependencies to ensure that the task is not executed multiple times in the same run.
- Provide more context or code examples: If the provided steps do not help you resolve the error, please provide more details about your project structure, Gradle configuration, and the specific task that is causing the issue. By providing relevant code examples, others can offer more specific guidance on how to resolve the error.
