Affects PMD Version:
6.48.0 (but works fine in 5.8.1)
Rule:
UnnecessaryImports
Description:
Nested classes (non-static and static) can be imported using on-demand import and static nested classes can be imported with on-demand static import. For both cases PMD will show 'Unused import X.X.X`
Code Sample demonstrating the issue:
package net.sourceforge.pmd.lang.java.rule.codestyle.unnecessaryimport.package2;
public class C {
private C() { }
public class IC {}
public static class ISC {}
}
package net.sourceforge.pmd.lang.java.rule.codestyle.unnecessaryimport.package1;
import net.sourceforge.pmd.lang.java.rule.codestyle.unnecessaryimport.package2.C.*;
public class U {
IC c;
}
package net.sourceforge.pmd.lang.java.rule.codestyle.unnecessaryimport.package1;
import static net.sourceforge.pmd.lang.java.rule.codestyle.unnecessaryimport.package2.C.*;
public class U {
ISC sc;
}
Expected outcome:
PMD reports a violation Unused net.sourceforge.pmd.lang.java.rule.codestyle.unnecessaryimport.package2.C, but that's wrong. That's a false positive.
