This file describes some minimum 'stuff one needs to know' to get started coding in this project.
The project's source code is hosted at:
Pull requests should be merged without fast forwards '--no-ff'. An easy way to achieve that is to use
% git config branch.master.mergeoptions --no-ff
The minimum required Maven version is 3.0.0.
Do note that there are some compatibility issues with Maven 3.X still unsolved 1. This is specially true for the 'site' plugin 2.
To run the unit tests:
% mvn -Phudson-tests test
Generating reports from unit tests:
% mvn install site
Running tests individually
% mvn -Phudson-tests -DfailIfNoTests=false -Dtest=<test-name> test
where <test-name> is the name of the Test class without its package name
To run an example firstly make sure you have run
% mvn -Prelease install
If the project version has already been released then this is unnecessary.
then you will need to set the following maven options, on Linux by
export MAVEN_OPTS="-Xmx1024m -XX:MaxPermSize=512m"
and the finally run the examples by
% mvn verify
You can also run individual examples by running the same command from the directory of which ever example you want to run. NB for this make sure you have installed examples/common.
% mvn -Prelease install
% mvn -Prelease package
We recommend using Eclipse Indigo (3.7) or Eclipse Juno (4.2), due to the built-in support for Maven and Git. Note that there are still some Maven plugins used by sub-projects (e.g. documentation) which are not supported even in Eclipse Juno (4.2).
Eclipse m2e is already included in "Eclipse IDE for Java Developers", or it can be installed from Eclipse Juno release repository.
HornetQ uses JBoss Logging and that requires source code generation from Java annotations. In order for it to 'just work' in Eclipse you need to install the Maven Integration for Eclipse JDT Annotation Processor Toolkit m2e-apt. See this JBoss blog post for details.
Eclipse Indigo (3.7) has out-of-the-box support for it.
As of this writing, Eclipse Juno (4.2) still lacks support for Maven's javacc plugin. See this post on the m2e connector for javacc-maven-plugin for manual installation instructions (as of this writing you need to use the development update site).
Importing all HornetQ subprojects will create too many projects in Eclipse, cluttering your Package Explorer and Project Explorer views. One way to address that is to use Eclipse's Working Sets feature. A good introduction to it can be found at a Dzone article on Eclipse Working Sets.
Eclipse code formatting and (basic) project configuration files can be found at
the etc/ folder. You should manually copy them after importing all your
projects:
for settings_dir in `find . -type d -name .settings`; do
\cp -v etc/org.eclipse.jdt.* $settings_dir
done
Do not use the maven-eclipse-plugin to copy the files as it conflicts with m2e.
HornetQ accepts contributions through pull requests on GitHub. After review a pull request should either get merged or be rejected.
When a pull request needs to be reworked, say you have missed something, the pull request is then closed, at the time you finished the required changes you should reopen your original Pull Request and it will then be re-evaluated. At that point if the request is aproved we will then merge it.
Make sure you always rebase your branch on master before submitting pull requests.
