Subject cvs commit: ant/src/main/org/apache/tools/ant/taskdefs/optional/dotnet DotnetBaseMatchingTask.java DotnetCompile.java Ilasm.java NetCommand.java
Date Mon, 10 Mar 2003 08:02:25 GMT
stevel      2003/03/10 00:02:25

  Modified:    src/main/org/apache/tools/ant/taskdefs/optional/dotnet
                        DotnetCompile.java Ilasm.java NetCommand.java
  Added:       src/main/org/apache/tools/ant/taskdefs/optional/dotnet
                        DotnetBaseMatchingTask.java
  Log:
  refactoring so that ilasm can share code (and moved something into NetCommand as it may
be more at home there, but that may be bogus). Fixed  ilasm to handle multiple files and do
dependency checking. More convoluted than one would have thought.
