I have difficulty creating a memory dump for my unit tests which produce out of memory errors.
My MAVEN_OPTS contains the following:
-Xmx1024m -XX:-HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=C:\Temp
However, when I run my unit tests from the command line using "mvn install", I do not get any such memory dump when the OutOfMemoryError occurs.
How do I get the memory dump?
Thanks
Maven (surefire-plugin to be precise) by default creates new JVM for running tests. MAVEN_OPTS variable is used by the JVM running maven itself, but not forked test JVM. To change settings of that JVM, use the following code snippet:

I tried running the testcases by using robotframework-2.8.6 jar like below
java -jar robotframework-2.8.6.jar testcases
But Its not recognizing the selenium2keywords. How do I use the selenium2library with robotframework jar ?
The easiest (and most robust/enhanceable) way to use the robot framework jar file is through the maven plugin.
(I'm assuming here that you have a maven runtime)
Just create a pom file that uses the plugin and run it using mvn install
Adding selenium 2 becomes just a matter of adding a dependency to the pom file.
Example (with selenium 2) which contains some useful tricks in it as well.

I am getting package org.testng.annotations does not exist error when I am trying to compile multiple source directories using maven. I am running webdriver tests and all of my tests are importing import org.testng.annotations. I am using IntelliJ 12 and my src directory looks like this -

why am I getting the org.testng.annotations not found error?
The default layout for a maven project is the following:
src
main
java
test
java
within the src/main/java/ directory the package name for you productive java class source files should added. within the src/test/java/ the package name for the unit tests java class source files.
And you should NOT change the layout if you don't have really really good reasons to do so.
Furthermore redefining the defaults of Maven defaults (target, target/classes, target/test-classes etc.) is against the convention over configuration paradigm.
Be aware that you need to follow a naming convention for unit tests which means you unit tests should be named like the following:
<includes>
<include>**/*Test*.java</include>
<include>**/*Test.java</include>
<include>**/*TestCase.java</include>
</includes>
But in your case I assume that we are talking about integration tests which means you need to use the following naming convention
<includes>
<include>**/IT*.java</include>
<include>**/*IT.java</include>
<include>**/*ITCase.java</include>
</includes>
Apart from that you should now that unit tests in Maven will be executed by the maven-surefire-plugin whereas the integration tests will be executed by the maven-failsafe-plugin.
To get around the testng annotations not found errors I ended up moving the base class from src/main/java/package1/baseclass.java to src/main/test/package1/baseclass.java and the testng annotations errors resolved
I'm new to Maven, and have been running into some difficulty in a project. I am to convert a Maven 1 project into Maven 2.
I started with these files:
maven.xml -- contains custom build scripts
project.properties -- general build settings
project.xml -- Project Object Model (POM) definition
From my understanding, Maven 2 project I must move these files into these:
pom.xml -- POM definition
(and possibly) settings.xml -- local configuration
I have gone about this by using the command 'mvn one:convert'.
This seemed to take care of project.xml > pom.xml
I then added a to pom.xml to include project.properties (which seemed to work).
Am I right in assuming that all I have left is to transfer over the contents of maven.xml >> pom.xml ?
maven.xml starts with:
<project default="site_deploy"
xmlns:ant="jelly:ant"
xmlns:maven="jelly:maven"
xmlns:j="jelly:core"
xmlns:util="jelly:util">
<ant:property environment="env"/>
and contains contains goals such as:
<goal name="site_deploy">
<attainGoal name="clean"/>
<attainGoal name="clean:clean"/>
<ant:delete dir="${maven.src.dir}/core/target" />
<attainGoal name="core_deploy"/>
</goal>
<goal name="core">
<maven:maven
descriptor="core/project.xml"
goals="jar:install"/>
<ant:property name="m2Dir" value="${maven.repo.local}/../../.m2/repository/app/${application.version}"/>
<ant:property name="m1Path" value="${maven.repo.local}/${application.id}/jars/${application.id}-core-${application.version}.jar"/>
<ant:echo message="copying jar m1 to m2 (${m1Path}) to (${m2Dir})" />
<ant:mkdir dir="${m2Dir}"/>
<ant:copy todir="${m2Dir}" file="${m1Path}" />
</goal>
From my reading if not bound to any build phase, goals can be executed outside of the build lifecycle by direct invocation, the second way being to write plugins for the goals.
How would I identify if the goals have dependencies-- how would I go about writing a plug-in? I've been referring mostly to the maven guides on apache.org, but some of it is hard to follow.

I have a Maven project that generates a WAR file and tries to get the artifact version from properties in .properties files that are maintained in the codebase. I also try to form the final name of the WAR file using custom properties.
Snippet :

The name of the WAR file gets generated properly when I do a "mvn clean package" :
[INFO] Assembling webapp[webapps] in [/home/jubuntu/workspace/ui/new/webapps/target/webapps-2.8-qa]
[INFO] Processing war project
[INFO] Copying webapp resources[/home/jubuntu/workspace/ui/new/webapps/webapps-main/src/main/webapp]
[INFO] Webapp assembled in [4690 msecs]
[INFO] Building war: /home/jubuntu/workspace/ui/new/webapps/target/webapps-2.8-qa.war
But when I do a "mvn clean install" ( or a "mvn clean deploy" ) , the properties don't expand for some reason (the package phase still generates the WAR with the right name) :
[INFO] Building war: /home/jubuntu/workspace/ui/new/webapps/target/webapps-2.8-qa.war
[INFO] [install:install {execution: default-install}]
[INFO] Installing /home/jubuntu/workspace/ui/new/webapps/target/webapps-2.8-qa.war to /home/jubuntu/.m2/repository/com/xyz/webapps/webapps/${info.version}-${application.env}/webapps-${info.version}-${application.env}.war
Is there something wrong that I'm doing here ? How would I make this work for installing and deploying my artifact ? I use maven version 2.2.1 for my builds. Thanks.
You can't do this. It's not supported by Maven. It's fundamental.
I've been trying to use writepom using this http://maven.apache.org/ant-tasks/examples/write-pom.html as a reference and have been having problems. I'm essentially just trying to test whether it will actually work so the POM file is quite bare. See below.

I get this error when I try to run ant
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-antrun-plugin:1.0:run
(compile) on project maven-setup:

following error occurred while

java.lang.NoSuchMethodError:
org.apache.maven.settings.RuntimeInfo.(Lorg/apache/maven/settings/Settings;)V
-> [Help 1]
I'm not sure if it's relevant, but before I added the typedef I was getting this error:
[ERROR] Failed to execute goal

Could not create task or type of type:

Sorry for the most likely basic question, but I can't seem to fix this myself.
[EDIT]
Here's the pom.xml file which I use to run the ant build.

The problem with the project only exists when running the maven task "mvn generate-sources" (see pom.xml above). When I just run "ant" it builds successfully. Any insight is greatly appreciated.
This script runs fine, provided you've put maven-ant-tasks-2.1.1.jar into the same directory where your build.xml lives.
The errors you are encountering tell me that the path may be incorrect.
Also, it's better not to set basedir attribute of your project and use a default ( current directory of the build.xml )
Last, but not least, artifact:writepom pomRefId should match the id of artifact:pom.
Below is the script:
<project
