The one line file: public class Foo extends antrl.LLkParser { Foo() { super (0); } } compiles with JAVAC: javac -classpath .;antlr.jar Foo.java But does not compile with Eclipse even though antlr.jar is in the project classpath. Complete reproduction scenario: File->New Java Project "antlrbug" Right MouseButton->New Folder "lib" Copy antlr.jar (http://www.antlr.org) into /lib Refresh, File->Project Properties Right MouseButton->Properties->Libraries->Add JARs->select "antlr.jar" Right MouseButton->New Class Name: "AntlrBug" Super Class: Select LLkParser Generate inherited constructors Now Eclipse has a file it cannot compile, error message "The compilation unit indirectly references the missing type antlr.debug.TraceListener (typically some required class file is referencing a type outside the classpath" It's as if Eclipse has an older version of antlr.jar in its plugins so the "auto-compilation" fails. What an Open-Source compiler writer to do when using an Open-Source IDE :-) Thanks, Chris
Reproduced
When we check inherited methods from antlr.Parser void removeTraceListener(antlr.debug.TraceListener) we fail to bind antlr.debug.TraceListener. Other compilers seem to ignore this missing type, since the #removeTraceListener isn't considered in the compilation process. We could be somewhat more lazy and not resolved these methods unless they are relevant to the sources we are compiling (overriden, abstract etc...). Post 2.1
Same issue as bug 21661. To fix, we need to ask for inherited methods named the same as the current type & all abstract methods which need to be overridden... plus some other categories likely. It will slow down the method verifier. *** This bug has been marked as a duplicate of 21661 ***
