Subject [jira] Created: (DERBY-1079) Build javadoc under jdk 1.6
Date Tue, 07 Mar 2006 00:15:29 GMT
Build javadoc  under jdk 1.6

         Key: DERBY-1079
         URL: http://issues.apache.org/jira/browse/DERBY-1079
     Project: Derby
        Type: Bug
  Components: Build tools  
    Reporter: Rick Hillegas
     Fix For:

We would like to build the javadoc under 1.6 so that all of the classes (including the JDBC
3 and JDBC 4 support) end up in the same directory tree. This is particularly important for
the published API which we expose to end-users.

Right now you can do the following:

1) Build the whole codeline using the 1.4 compiler for most classes and the 1.6 compiler for
the JDBC4 support.

2) Build javadoc in a 1.4 environment (with JAVA_HOME set to 1.4). This runs step (1) if it
has not already happened. This javadoc excludes the JDBC4 support because generics-laden JDBC4
signatures choke the 1.4 compiler.

3) Build the javadoc in a 1.6 environment (with JAVA_HOME set to 1.6). This will fail if you
have not run step (1); this is because you can't build Derby in a 1.6 environment yet. This
also generates a number of warnings because the 1.6 javadoc tool objects to code generated
by the JAVACC grammar tool; JAVACC turns out code with loop variables distastefully named
"enum". In addition, today, the 1.6 javadoc excludes the JDBC4 support.

We would like to end up with the following situation:

a) If your ant.properties points at a 1.6 installation, then the javadoc targets will use
the 1.6 javadoc tool and will include Derby's JDBC4 support. This will work regardless of
whether you have already built the class tree. If you have not already built the class tree,
then we will compile it under scenario (1) above.

b) If, however, your ant.properties does not point at a 1.6 installation, then the javadocs
target will continue to use the 1.4 javadoc tool to build only the classes built today. The
JDBC4 support will be excluded from this javadoc.

c) As part of releasing 10.2, we will build the javadoc under scenario (a).

d) Once 1.6 exits beta and becomes a production vm, the community can debate when we want
to fix DERBY-1078 and require 1.6 in the build environment.
