I am building a number of maven projects from the level of their parent.Some of the projects have child modules of their own. Is there a way to print the time-stamp after each module is built?
I suggest using the maven ant-run plugin.
You can add an execution bound the last step (install or deploy) which will print out the time stamp of your choice.
See examples here.
Also you can try the maven exec plugin and just run the system command date (linux) or date /T (windows).
I hope this helps.

I am working with an automatic build script in maven 3.x. The parent project contains of more than 60 modules. The compilation is done in a shell script simplified this way:
for each module:
cd module
mvn clean install > compile.$module.log
echo "Compiled $module"
I like to see a list of compiled modules in order to see the progress or the build. I like to have a big maven command and avoid the manual for loop. I hope to speed up the build this way, since splitting the parent project into more independent modules is not a short time option, yet.
The --quiet flag might be enough already. Alternatively a user defined logging implementation would be fine as well, as described in the manual (https://maven.apache.org/maven-logging.html)
The questions are:
What is the prefered way to modify maven log output?
Does anyone already know a ready-to-use plugin for my purpose?
Thanks
I would like to use Maven to produce an artifact in zip format. To give you some background; my project includes an APS package (Application Packaging Standard, used to provision cloud applications on the Parallels platform). This package is a zip file that contains a combination of XML as well as PHP files. It is generated by an APS plugin from within Eclipse and its name always includes the version and release number of its contents.
What I am trying to do is generate a zip file with Maven that would be kind of a release candidate that will be eventually sent to customers and would include not only the actual APS package but also other files such as README, User Guide.pdf, etc;. I would like the name of this zip file to contain the version number of the version number of the APS package. Currently I can generate this manually by using something like "mvn -Dversion=1.2.3-4 package" but I would like to automate the process and ideally run this from Jenkins.
Basically, my strategy is to run a script that would extract the version number from the initial APS package, once that is done, my script can invoke Maven and can pass this parameter to it so it can generate the final zip with the proper version number. This is fine but again, I need to run this script manually and I am looking for an automated process.
My question is; is it possible to invoke this script from within Maven and use its return as a parameter to set the version name (or the name of the file that will be generated) at run time? As I mentioned, I would like eventually Jenkins to handle this. It can pick up the pom file but I am not sure how it could kind of "auto configure" itself to have the proper version number.
Thanks is advance.
From jenkins build you can use profile with ${BUILD_NUMBER}:
<profile>
<id>jenkins</id>
<build>
<finalName>${artifactId}-${version}-${BUILD_NUMBER}</finalName>
</build>
</profile>
Then run in jenkins:
clean install -Pjenkins
I use the SVN (or any source versioning system) version to identify the software builds.
By simply executing this
REVISION=`svn info | grep '^Revision:' | sed -e 's/^Revision: //'`
on the sourcers folder you get the right value in $REVISION, then you can use it for your maven build
mvn -Dversion=1.2.3-$REVISION package
easy and clean
I have a script on Jenkins CI which optionally does dependency:go-offline. The other option should be to do nothing. But I can't put "" in there - it must be a goal.
So - which one would you pick? It should:
Be in central, always reachable
Take minimum time
Have minimal output
Have no side effects
I was thinking of some help:... goal but those tend to have a lot of output. Any better?
You can use this goal and option:
mvn --quiet help:help
the -q,--quiet option causes the output to only show errors.
Note that Jenkins allows you to add options like --quiet as diplayed in the usage: mvn [options] [<goal(s)>]. You configure these in the Jenkins job’s “Goals and options” field.
Check mvn --help output for further information.
I know this is an old question, but I came across it when I had the same requirement and it's still unanswered, so I'm posting for anyone who needs it in future.
This still depends on the current project, but could be useful if you don't want to hardcode a specific plugin for some reason:
mvn -pl ./ validate
-pl ./ means only current project, ignore submodules. Alternatively you could specify specific project by relative path or [groupId]:artifactId.
validate is the first phase of the Default Lifecycle. Doesn't change or build anything.
Alternatively, if you don't have a maven project at all, some maven plugins, or rather specific plugin goals, can be executed without it. E.g.:
mvn org.apache.maven.plugins:maven-dependency-plugin:2.1:help
It would still scan projects if it sees a POM in the current directory. And of course you still need to have the plugin in your local repository.
We would like to have a script that does "svn update" and if the depedency.gradle file is in that list of updates, we would like to run a task that ONLY updates dependencies so the developers machine is up to date. What would that task be? I don't see it when running "gradle tasks". Looking for an updatejars or something.
When we build our project, we don't want it to check for jar updates at all!!!! most because that only needs to be done in 2 situations which are #1 above and when someone is updating the dependency.gradle file themselves. For the second thing, they can just run "gradle updatejars" once I know the answer to question #1 that is.
Any ideas? I am just getting into gradle and we really want to keep a consistent environment where when we run our update script, it gets the source code AND the jars in one atomic sweep and we are no longer bothered by checking the repositories every build.
It would be nice to know how to do it by changing the build.gradle file if possible. If not, is there a command line option? (The build.gradle obviously would give me a command line option which is why I prefer that method as I could say compile does not depend on downloading jars).
Regarding the second question. As far as I understand, Gradle will not attempt to do remote lookups or try to download the jar if it is already in the local cache. This should be true for jars declared with a static version, e.g. testCompile 'junit:junit:4.10'.
If you have dynamic versions, e.g. 1.+ or 1.0-SNAPSHOT, etc. then Gradle has to do a check every now and then. You can fine tune the cache expiry for such dependencies.
To make sure Gradle does not do remote lookups you can also use --offline option. See this doc for details.
With regard to svn update, you have at least 3 options:
Try to use an SvnKit plugin for Gradle
Use the ant svn task (here's how to do svn checkout)
Run external command from Gradle. Use the ExecPlugin or just implement it yourself using Groovy API.
Looks like the 1st question I can do with the answer in this post
how to tell gradle to download all the source jars
so I can just gradle eclipse and it will download new jars and update my classpath...nice.
This is more of aesthetic question since I want to make my life easier. I have maven project structure like this:
foo-project (parent)
foo-business (child-module)
foo-dao (child-module)
foo-app (child-module)
I run my maven commands from command prompt, I want to trigger install of all project from maven module, meaning if I am in module dir I want to trigger install from there and not to navigate to parent pom dir.
Thank you
If you really want to make your life easier, separate your parent project (i.e. the one where you put common settings for your other projects) from your aggregator project (i.e. the one that has your other projects as modules). At that point the sole purpose of your aggregator project will be to let you build all your projects together, so run your builds from there.
With Maven, doing as Maven likes is always going to make your life easier than any other option.
Consider using Buildozer - an utility that I wrote some time ago in order to cleverly perform builds of given module, but building all "outdated" dependencies first.
It can be downloaded here: http://buildbox.sourceforge.net/buildozer/
It requires that you first register your modules (= create mapping between dir and GAV for each module), like this:
zer reg /home/pkozelka/my-common-modules /home/pkozelka/my-projects
or
cd /home/pkozelka/other-modules
zer reg .
then you go into any module and perform the build:
zcd my-server # this is 'chdir by artifactId', with bashcompletion on Linux
zer . # compiles all (transitive) dependency modules and then this one
