Exorbitant long site-build since surefire 2.4
---------------------------------------------
Key: SUREFIRE-562
URL: http://jira.codehaus.org/browse/SUREFIRE-562
Project: Maven Surefire
Issue Type: Bug
Components: report plugin
Affects Versions: 2.4.3, 2.4.2, 2.4.1, 2.4
Reporter: Jörg Hohwiller
When I have maven-surefire-report-plugin and maven-surefire-plugin in version
2.3,
my site-generation works quite okay.
However when I update to 2.4, 2.4.1, 2.4.2 or 2.4.3 the site-build takes an
exorbitant long time.
When you watch the log, you get the impression that there is an infinity-loop
because it
builds the same modules again and again. However it is not an infinity loop but
I think that for every
module also all dependent modules are build (and therefore tested) recursively
even if they had
already been build before.
This way 2.4 scales from O(n) to O(n^2) where n is the number of modules when
you have
common inter-project dependencies.
Maybe some feature in 2.4 like improve coverage measure with cobertura or
whatever
introduced this bug.
Infos about mvn site:stage with surefire 2.3:
Total time: 18 minutes 19 seconds
Size of logfile (mvn output): 3.567.441 bytes
grep "Building util-core" site.log | wc -l: 44
Infos about mvn site:stage with surefire 2.4.3:
Total time: 70 minutes 29 seconds
Size of logfile (mvn output): 58.442.755 bytes
grep "Building util-core" site.log | wc -l: 130
FYI: util-core is the name of a module that all other modules depend on
directly or transitive.
Besides in the 2.3 build only 1 of the 44 lines with "[INFO] Building
util-core" is followed with
[INFO] task-segment: [site:stage]
All other 43 are followed by some --- and then
[INFO] No goals needed for project - skipping
The extra lines in the 2.4 build are followed with some ---- and then
[INFO] [resources:resources]
...
Please also note that the maven logfile is totaly unreadable since you have no
clue where a recursive invocation starts and ends. This is more an MNG issue,
however...
