----------------------------------
Resolution: Fixed
> uv3 migration tool design fixes
> -------------------------------
>
> Key: UIMA-5421
> URL: https://issues.apache.org/jira/browse/UIMA-5421
> Project: UIMA
> Issue Type: Bug
> Components: Core Java Framework, Tools
> Affects Versions: 3.0.0SDK-alpha02
> Reporter: Marshall Schor
> Assignee: Marshall Schor
> Fix For: 3.0.0SDK-beta
>
>
> The design for the migration tool has some defects. The main one is it
> should migrate all versions
> # the migrate from sources vs from classes should operate differently:
> ## sources
> ##* migrate the source, no subsequent compilation; no reassembly (in Jars or
> PEARs)
> ##* if in a Jar or PEAR, issue message saying Jar or PEAR will need to be
> rebuilt and advising to delete the xxx_Type.java files.
> ## classes
> ##* decompile. Always use the original byte array for decompiling (current
> impl switches to the version from the classpath). Arrange the migrate
> classpath to put any Jar or Pear-classpath in front.
> ##* do a compile using above modified migrate classpath (plus the uv3 core in
> front) and reassembly step (if class was found in Jars or Pears, an no
> compile errors) by copying the original assembly and updating the class part.
> # change the output naming convention to support multiple compiled migrations
> - for example, having the same class inside multiple updated Jars, with
> obvious tracking between the output pathnames and the original.
> # update the version of the parser and decompiler dependencies to the current
> versions
> # update the documentation.
> # properly handle jars containing pears, pears containing jars.
> # allow no migrate classpath when migrating from classes (useful for
> migrating Pear files)
> # break the compile step for a container into multiple sets of compilation
> units, if different versions exist for the same classname (otherwise get
> compiler error - duplicate definition)
> # print out all compiler errors and messages
