[jira] Created: (MJAVADOC-171) Modules in multi-module projects are
"built" too often
Modules in multi-module projects are "built" too often
------------------------------------------------------
Key: MJAVADOC-171
URL: http://jira.codehaus.org/browse/MJAVADOC-171
Project: Maven 2.x Javadoc Plugin
Issue Type: Bug
Affects Versions: 2.3
Environment: Maven 2.0.8, Linux
Reporter: Stefan Seidel
Priority: Critical
Attachments: mvnexec.zip
In a multi-module project, all modules are "built" twice for each module. This leads to huge performance problems when many modules are in a project. In the attached sample project, the xmlbeans plugin is executed 27 times for a project with one parent module and two submodules. 18 of these executions can be attributed to the javadoc plugin. With version 2.2, only 3 invocations (once for each project) are caused by the javadoc plugin.

Attachment: mjavadoc-171-b.zip
ok, I reproduced the case with every m-javadoc-p version, and with Maven 2.2.1
here is the result (and the script to calculate it):
{noformat}$ ./mjavadoc-171.sh
Apache Maven 2.2.1 (r801777; 2009-08-06 21:16:01+0200)
Java version: 1.5.0_22
Java home: /home/opt/jdk1.5.0_22/jre
Default locale: fr_FR, platform encoding: UTF-8
OS name: "linux" version: "2.6.38-11-generic" arch: "amd64" Family: "unix"
m-javadoc-p 2.0: 3 xmlbeans, 0 compiler
m-javadoc-p 2.1: 3 xmlbeans, 0 compiler
m-javadoc-p 2.2: 3 xmlbeans, 0 compiler
m-javadoc-p 2.3: 18 xmlbeans, 0 compiler
m-javadoc-p 2.4: 0 xmlbeans, 0 compiler
m-javadoc-p 2.5: 24 xmlbeans, 8 compiler
m-javadoc-p 2.6: 24 xmlbeans, 8 compiler
m-javadoc-p 2.6.1: 24 xmlbeans, 8 compiler
m-javadoc-p 2.7: 24 xmlbeans, 8 compiler
m-javadoc-p 2.8: 24 xmlbeans, 8 compiler{noformat}
Here is a few facts I got that can explain some results:
- test-javadoc goal was added in m-javadoc-p 2.3
- javadoc-aggregate and test-aggregate were added in m-javadoc-p 2.5, and they "Invoke the execution of the lifecycle phase generate-sources prior to executing itself."
this does not really explain why, but here are some facts
some numbers are different from yours: can you run the script on your machine and share your results?

------------------------------------
How many times ...
Sorry, but saying it's fixed doesn't mean it is. Why can you not just add a unit test?
Here's an addition to the list:
2.8: 26
Sorry to be a nuisance, but what can I do to finally get my site build run properly? Especially since 2.2 or 2.4 do not work with the maven-site-plugin:3.0?

Stefan Seidel reopened MJAVADOC-171:
------------------------------------
And added it again in 2.5
Here are the number of xmlbeans occurences by version:
2.2: 5
2.3: 20
2.4: 0
2.5: 26
2.6.1: 26
2.6: 26
2.7: 26
AFAICS, only 2.2 behaved correctly.

-----------------------------------
Attachment: mjavadoc-171.zip
This seems to be a problem with your local build environment. The maven-users mailing list is quite helpful in such cases.
Anyway, here's a cleaner version, for convenience already with the plugin version via system property.
Run:
{code}
unzip mjavadoc-171.zip
mvn clean site -Djavadoc.plugin.version=2.8 | grep xmlbeans | grep execution | wc -l
{code}
(and replace the value for javadoc.plugin.version with the version to test).
Exact numbers may differ slightly, but the overall tendency is equivalent.

Oh, and the "Maven 3" part of the pom.xml only is there to show that with Maven 3 and the maven-site-plugin:3.0 the problem is the same (even though only versions 2.7 and 2.8 of maven-javadoc-plugin run sucessfully under Maven 3 + maven-site-plugin 3.0).

ok, I reproduced the case with every m-javadoc-p version, and with Maven 2.2.1
here is the result (and the script to calculate it):
{noformat}$ ./mjavadoc-171.sh
Apache Maven 2.2.1 (r801777; 2009-08-06 21:16:01+0200)
Java version: 1.5.0_22
Java home: /home/opt/jdk1.5.0_22/jre
Default locale: fr_FR, platform encoding: UTF-8
OS name: "linux" version: "2.6.38-11-generic" arch: "amd64" Family: "unix"
m-javadoc-p 2.0: 3 xmlbeans, 0 compiler
m-javadoc-p 2.1: 3 xmlbeans, 0 compiler
m-javadoc-p 2.2: 3 xmlbeans, 0 compiler
m-javadoc-p 2.3: 18 xmlbeans, 0 compiler
m-javadoc-p 2.4: 0 xmlbeans, 0 compiler
m-javadoc-p 2.5: 24 xmlbeans, 8 compiler
m-javadoc-p 2.6: 24 xmlbeans, 8 compiler
m-javadoc-p 2.6.1: 24 xmlbeans, 8 compiler
m-javadoc-p 2.7: 24 xmlbeans, 8 compiler
m-javadoc-p 2.8: 24 xmlbeans, 8 compiler{noformat}
Here is a few facts I got that can explain some results:
- test-javadoc goal was added in m-javadoc-p 2.3
- javadoc-aggregate and test-aggregate were added in m-javadoc-p 2.5, and they "Invoke the execution of the lifecycle phase generate-sources prior to executing itself."
this does not really explain everything, but since no reportSet has been defined these aggregate reports are run in addition to non-aggregate reports: see MSITE-454 for thought about avoid this by default, because it is not really expected by users
some numbers are different from yours: can you run the script on your machine and share your results?

[jira] Updated: (MJAVADOC-171) Modules in multi-module projects are

Posted by "Stefan Seidel (JIRA)" <ji...@codehaus.org>.

Stefan Seidel updated MJAVADOC-171:
-----------------------------------
Attachment: 2.2.log
It's not about twice. It's about _all_ modules are built twice for _each_ module. I have removed the maven-surefire-report-plugin from the parent pom (to show the problem more distinctively) and when I run clean site the following logs come out with version 2.3 and 2.2 respectively. Notice the vast increase of
{code}
[INFO] Building Unnamed - org.test.forked:...
[INFO] ------------------------------------------------------
[INFO] [xmlbeans:xmlbeans {execution: default}]
[INFO] Nothing to generate.
{code}
parts from 2.2 to 2.3.

Herve Boutemy commented on MJAVADOC-171:
----------------------------------------
IMHO, it's about m-javadoc-p having 4 goals, each having @requiresDependencyResolution compile
and the way Maven core needs to actually *run* scopes to do the resolution, and it does it multiple times
I still don't understand everything, nor have an idea if it's a bug or unexpected consequence of a feature
but it lead me to a workaround: if you define reportSets with less than the 4 reports, you'll divide the number of executions
if you configure javadoc report only, without test-javadoc or aggregate versions like this:
{code:xml}<plugin>
<artifactId>maven-javadoc-plugin</artifactId>
<version>2.8</version>
<reportSets>
<reportSet>
<reports>
<report>javadoc</report>
</reports>
</reportSet>
</reportSets>
</plugin>{code}
the multiple executions will disappear (and a lot of m-javadoc-p version will simply blow up, I didn't study why, just came to the conclusion that new versions have less bugs than old ones)

----------------------------------
Attachment: mjavadoc171.patch
FYI, I can't get maven-javadoc-plugin to "mvn install" from trunk (I get test failures), but the 2.3 tag builds just fine; when I remove the @aggregator tag from the mojo, it seems to work perfectly. I hypothesize that @aggregator is seriously broken, at least for reporting plugins (or perhaps just plugins that need to @execute forked lifecycles like this one), and at least in this case, it seems to be harmful and unnecessary.

---------------------------------------
I think I am running into the same problem with version 2.7 and maven 3. It is trying to fork compilations of sibling projects... Basically it ends up running out of heap space.

------------------------------------------
Don't know about xmlbeans plugin, but the javadoc plugin generates javadoc for main and test so twice sounds correct.
Could you give me a log file and point me the lack of execution?

----------------------------------------
Hmm.I have created a test project and attached it to this issue long time ago. I've attached the log files and explained (hopefully clearly) what the difference is and what the problem is. Now what else is there what would be different for a new issue? And what makes you sure that you have fixed this issue?
The numbers I provided are: extract the "mvnexec.zip", run mvn site, count the number of xmlbeans invocations. I hope this is now reproducible.
