These error messages are to be expected. I agree BUILDING.txt should warn people to expect this, I agree it is disconcerting.

Hi,

I ran across an interesting issue while building Derby. I checked out the latest sources and ran ant from the top. I read the ant output and found this:

genParser:
     [echo]   Generating SQL parser...
     [java] Java Compiler Compiler Version 4.0 (Parser Generator)
     [java] (type "javacc" with no arguments for help)
     [java] Reading from file sqlgrammar.jj . . .
[java] Note: UNICODE_INPUT option is specified. Please make sure you create the parser/lexer using a Reader with the correct character encoding. [java] Warning: ParseException.java: File is obsolete.

Please rename or delete this file so that a new one can be generated for you.
     [java] Parser generated with 0 errors and 3 warnings.

Thinking I had done something wrong, I followed instructions and removed the 3 obsolete files. Now I could not build any more. I got messages like this:

genParser:

compile:
    [javac] Compiling 149 source files to /Users/clr/derby/trunk/classes
[javac] /Users/clr/derby/trunk/java/engine/org/apache/derby/impl/sql/compile/ParserImpl.java:141: cannot find symbol
    [javac] symbol  : method ReInit(java.io.Reader,int,int,int)
    [javac] location: interface org.apache.derby.impl.sql.compile.CharStream
[javac] charStream.ReInit(sqlText, 1, 1, LARGE_TOKEN_SIZE);

Once I went back and restored the three files to their checked-in versions, everything worked again.

This indicates to me that the sources for these three files in sqlgrammar.jj are not in sync with the generated java files. Was this intentional? Should we add a note in BUILDING.txt to explain what is going on?

Thanks,

Craig
