gleonSun opened a new issue, #8462:
URL: https://github.com/apache/incubator-gluten/issues/8462
### Backend
CH (ClickHouse)
### Bug description
[Expected behavior]
Gluten can load the required Components and Backend, and function normally.
[actual behavior]
Gluten failed to load the required Components and Backend during
initialization, resulting in abnormal execution.
### RootCause
The `ResourceUtil#getResources(java.util.regex.Pattern)` method loads
META-INF from the `java.class.path`, but it might not be the META-INF from the
project's corresponding resource directory. For example, when other projects
reference Gluten, it retrieves the META-INF from their resource directories
instead, which does not align with expectations.
