                        The `coverage -t` parameter encountered an error during execution.
When I execute the command
defects4j coverage -t org.apache.commons.lang3.AnnotationUtilsTest::testOneArgNull ,
I encountered an error message:
"BUILD FAILED Target 'org.apache.commons.lang3.AnnotationUtilsTest::testOneArgNull' does not exist in the project 'Defects4J'". However, I can successfully run the command
defects4j test -t org.apache.commons.lang3.AnnotationUtilsTest::testOneArgNull.
Why is this happening?
