How to exclude file on maven release:prepare and release:perform? - maven

I am using maven to release/tag my projects, and I am using some propery files and want mvn:prepare to exclude those under release. I tried using the following command:
mvn release:prepare -DpreparationGoals="clean install"
-DcheckModificationExcludeList=props.properties
But it still gives me the following error:
[INFO] Cannot prepare the release because you have local modifications :
[props.properties:unknown]
So the question is: how can ACTUALLY make maven mvn:release skip checking for certian local modifications? Thanks for your time.

This feature was implemented in version 2.1

What is the supported way to change version on deploy for Artifactory Maven Jenkins plugin

I'm using the Maven jfrog plugin: https://jenkins.io/doc/pipeline/steps/artifactory/#rtmavendeployer-set-maven-deployer
I want to change the version of the artifact on deploy so it has the feature branch name in it.
I tried to run the set version goal. It succeeds but just totally ignores the version
rtMavenRun (
pom: "pom.xml",
goals: 'versions:set -DnewVersion=1.2.3-SNAPSHOT clean install',
resolverId: 'resolver-unique-id',
deployerId: 'deployer-unique-id'
)
The problem is the following: You call the goal versions:set and the phases clean and install in one Maven run. Before the first goal runs, Maven has already resolved the version for all goals/phases that are run. Therefore, you change the version in the POM, but as Maven has already read it, you will not be able to see it during this run.
What are possible solutions?
You can run versions:set first and then clean install in a separate Maven run.
You can use the property ${revision} in the definition of <version> and then set this property on the command line.

How to generate maven artifact with jenkins build number

I'm trying associate maven artifacts name with build number.
ex: sample.1.0.0-snapshot.ear into sample.1.0.0-snapshot.buildnumber.ear
I have tried maven-buildnumber plugin but still no luck.
could anyone help me to do this.
You can use the Versions Maven plugin by executing following command before any other maven targets after clean.
mvn versions:set -DnewVersion=sample.1.0.0-snapshot.$BUILD_NUMBER

Why should run first mvn clean clover2:setup install clover2:clover, then: mvn sonar:sonar

Based on the question Sonar + Clover only runs on src-instrumented, it is suggested using first mvn clean clover2:setup install clover2:clover, then: mvn sonar:sonar.
Just wonder why we cannot use mvn clean clover2:setup install clover2:clover sonar:sonar?
In the past it was the recommended way to run goal sonar:sonar alone. This is no more the case since SonarQube Scanner for Maven stopped trying to run unit tests + collect coverage for you by forking a new Maven lifecycle.
General advice is now to run goals in a single command. For example mvn clean package sonar:sonar
In the case of Clover the clover:setup goal will alter the Maven Model to make all other plugins (like surefire) use instrumented classes instead of original source code. This is indeed a problem because it will prevent SonarQube to match class files. So in your case you should either stick with two separate goals, or manually configure sonar.sources to refer to original source code.
Compared the maven logs and found the possible reason:
The "mvn clean clover2:setup install clover2:clover sonar:sonar" seems having issue to find the Source dirs. The log shows it uses ${project}\target\clover\src-instrumented and ${project}\target\generated-sources\annotations as the source dirs.
If explicitly specify src/main/java, then this single command works well. The only tricky thing is why running the goals separately doesn't need to specify sonar.sources but the plugin can still find the right folder for source dirs.

Installing current version of DWR via Maven

I checked out current SVN Snapshot of DWR (3.0.0-rc3-SNAPSHOT) and I am unable to mvn install it - the pom.xml seem to be configured not for such command. What is the correct way of installing DWR into maven repo?
I also tried copying files from https://oss.sonatype.org/content/repositories/snapshots/org/directwebremoting/dwr/3.0.0-rc3-SNAPSHOT/ and mvn installing them as well. This way obviously does not work either. How can it be installed from here? I don't want to link to the snapshot directory directory from my pom.xml as I don't want to get unexpected results when new snapshot is introduced.
I'm not sure if I get you correctly, but you can always download the JAR and install it locally using Maven. Something like this:
mvn install:install-file -Dfile=dwr-3.0.0-rc3-20130514.180049-1.jar -DgroupId=org.directwebremoting -DartifactId=dwr -Dversion=3.0.0-rc3-SNAPSHOT -Dpackaging=jar
more on the Maven info here:
http://maven.apache.org/guides/mini/guide-3rd-party-jars-local.html
EDIT:
I managed to install it from source as well by do SVN checkout:
svn co https://svn.directwebremoting.org/dwr/trunk/
My first attempt to build it failed because I was using Maven 2.x. Seems like DWR is using Maven enforcer plugin to enforce certain Maven version. I didn't check which version is really required but by updating my Maven to Maven3 I managed to install it.

org.apache.maven.BuildFailureException: No SCM URL was provided to perform the release from

I'm using Maven 2.2.1 and I sucessfully ran:
mvn -B release:clean release:prepare
But get the error message:
No SCM URL was provided to perform the release from
when I run:
mvn release:perform
My pom.xml have the scm tags defined correctly:
<scm>
<url>file:///C:/tmp/svnrepo/myproj/trunk</url>
<connection>scm:svn:file:///C:/tmp/svnrepo/myproj/trunk</connection>
<developerConnection>scm:svn:file:///C:/tmp/svnrepo/myproj/trunk</developerConnection>
</scm>
It is possible to rerun a maven release:perform by creating a manually edited release.properties file in the root folder. This file should define these two properties: scm.url and scm.tag. Here a possible example:
scm.url=scm:git:https://github.com/owner/repo.git
scm.tag=v1.0.4
With this file it is possible to redo a release:perform task.
Inspired by this answer.
Looks like I did a mvn -DdryRun=true release:perform and this had deleted the release.properties file from the prepare stage.
So I add the -DconnectionUrl to the command to provide url of the tag
It should work. I had similar problem, but in my case perform failed due to network error and I had to restart it with something like:
mvn release:perform -rf :{ARTIFACT ON WHICH IT FAILED} -DconnectionUrl=scm:svn:{URL TO TAG}
The message
No SCM URL was provided to perform the release from
does not mean the SCM URL in the pom.xml!
There are two kinds of SCM-URLS:
Trunk Folder (for development)
Tag Folder (for tagging the release)
In the pom.xml you specify the trunk-folder-url. What the release:perform require is the tag-folder-url. You can specify the parameter -DconnectionUrl.
Usually you are using prepare and perform in one maven call. Prepare do all preparation stuff and will commit some resources to the version-control-system using the comment [maven-release-plugin] prepare release XXX- BUT NOT ALL FILES ARE COMMITTED! One important file is not committed to the version-control-system, the release.properties. This file is used if you omit the -DconnectionUrl.
The problem occourse while perform because the checkout/commit require the release.properties or the -DconnectionUrl respectivly.
You can either:
Specify the tag-url by using -DconnectionUrl or
Call release:prepare release:perform in one shot to rely on the not-committed release.properties

I got this same exception in our CI automation and it turned out to be due to the fact that target/checkout directory already has a release build. For one of the projects, we had to introduce an improvised maven release perform build between the real maven release:prepare and release:perform steps. As part of improvisation the release tag is checked out to target/checkout and what I noticed is that if this directory is left undeleted, it would cause the release:perform to fail with the No SCM URL was provided to perform the release from error. I don't know if it matters, but we also use -DlocalCheckout=true option.
Simply running mvn release:clean release:prepare first, and then mvn release:perform worked for me.
