It works for other files, > e.g. ArrayJava.java Hmm... "etags --help" doesn't seem to indicate that classes are tagged: etags --help --lang=c --lang=c++ --lang=java In C code, any C function or typedef is a tag, and so are definitions of 'struct', 'union' and 'enum'. '#define' macro definitions and 'enum' constants are tags unless you specify '--no-defines'. Global variables are tags unless you specify '--no-globals' and so are struct members unless you specify '--no-members'. Use of '--no-globals', '--no-defines' and '--no-members' can make the tags table file much smaller. You can tag function declarations and external variables by using '--declarations'. In C++ code, all the tag constructs of C code are tagged. (Use --help --lang=c --lang=c++ for full help.) In addition to C tags, member functions are also recognized. Member variables are recognized unless you use the '--no-members' option. Tags for variables and functions in classes are named 'CLASS::VARIABLE' and 'CLASS::FUNCTION'. 'operator' definitions have tag names like 'operator+'. In Java code, all the tags constructs of C and C++ code are tagged. (Use --help --lang=c --lang=c++ --lang=java for full help.) It says nothing about classes, only about class members? Can you post a Java file which has more-or-less complete class declarations, including the problematic one, and where some classes are tagged while others aren't? I'd like to try to figure out why some are tagged, but not others, and it's hard without an example. Please post the minimal example, to make stepping through the code easier. Thanks.
