调研方向
Start by locating the ProcessorTests infrastructure and the @ProcessorTest handling around Mappers.getMapper(MyMapper.class). Reproduce the issue by comparing the mapper's code-source location across test runs, then trace the class-loading behavior. Done means each test run can load the mapper implementation generated for that run rather than reusing the first-loaded class.

描述
Expected behavior
When a Mapper implementation is loaded in a test like
@ProcessorTest
void someTest() {
MyMapper mapper = Mappers.getMapper( MyMapper.class );
}
the loaded Mapper should be the one generated by the test. For example the one generated by Eclipse or JDK compiler.
Actual behavior
Currently a Mapper implementation is only loaded once from whatever test run loads it first.
This a limitation of the used class loading.
Steps to reproduce the problem
@ProcessorTest
void someTest() {
MyMapper mapper = Mappers.getMapper( MyMapper.class );
System.out.println( mapper.getClass().getProtectionDomain().getCodeSource().getLocation() );
}
You will see that the source code location does not change
