> NullPointerExceptions during PHPStan inspection
> -----------------------------------------------
>
> Key: NETBEANS-3002
> URL: https://issues.apache.org/jira/browse/NETBEANS-3002
> Project: NetBeans
> Issue Type: Bug
> Components: php - Code Analysis
> Affects Versions: 11.0, 11.1
> Environment: Windows 10
> Reporter: Czukowski
> Assignee: Junichi Yamamoto
> Priority: Major
> Attachments: PHPStanException.zip
>
>
> PHPStan code analysis support reports NullPointerExceptions at some
> occasions. When the exception occurs, the Inspect dialog window is not closed
> on its own.
> I've been able to reproduce it using the uploaded sample project. Run
> {{composer install}}, then configure NetBeans to use PHPStan from
> {{vendor/bin}} and the configuration from {{phpstan.neon}} file in the
> project root.
> The configuration file contains {{ignoreErrors}} section with a pattern to
> ignore known errors. The exception seems to depend on whether this pattern is
> there or not (to disable, comment the line with {{#}}).
> To reproduce, select the {{app}} folder and run PHPStan inspection with the
> scope: Current folder (app).
> With the setup above I've encountered two types of the stack traces:
> *Without ignore pattern (commented line)*
> Output:
> {code}
> "C:\Workspace\Test\PHPStanException\vendor\bin\phpstan.bat" "analyse"
> "--no-ansi" "--no-progress" "--no-interaction" "--error-format=checkstyle"
