Subject AW: Checkstyle
Date Wed, 27 Aug 2008 05:14:29 GMT
Here a snippet from our build.
We have three sourcefolders (src/main, src/test, src/junit), so I'll iterate over src/* later.


Line 2: Use Ants AntLib capability to load the checkstyle tasks. For that they must be on
Ants classpath. E.g. in ANT_HOME/lib, or added by "-lib" option (or via an Ivy dependency).

Line 4: Create a property "skip.checkstyle" if the flagfile is newer than all sources and
the cs-config file. This is a top level Ant task so it will be executed on each build and
before all targets.

Line 11: The CS-Target. It will be skipped if the property skip.checkstyle is set (to some
value) which means "no CS-Config-Change and no newer sources" which means: "work already done".

Line 12: Standard Ant behaviour: create the target directory.

Line 13: Create the flag file for comparison in Line 4. This makes the build faster.

Line 14+15: Ok, here I iterate over the three sourcefolders and just get the directory name
(c:/bla/bla/myproject/src/main --> main).

Line 24: Start of Checkstyle. Some properties are loaded from props-file.

Line 28: I change the taskname for better logging: display the name of the sourcefolder, like
  [mkdir]   bla bla
  [cs:main] bla bla

Line 30: Use the XML-Formatter of CS, so I can generate real reports later.

Line 31: Which files should be scanned - just my java sources?

Line 34-47: HTML-Generation. I use the XSL of Ant 1.7.1 (on that time not released, but now
:-) and tweak a little bit with the paths.

Line 50-53: Little "hacking": unset all properties needed in the loop.
