versions:
Autoshare
By default cloning a Git repo and then importing it as a Java or Maven project does not show it as "shared", meaning that the Eclipse project looks disconnected from your local Git repo. If you're used to work with SVN you might find this baffling, as you're accostumed to checkout a project from the central scm repository and see it connected to it, so that changes to your local copy are visually decorated by a special label or icon. In order to save you some clicks to achieve the same with Git you need to check the following option under Eclipse -> Preferences -> Team -> Git -> Projects
m2e 1.0 known issue
Indigo introduces m2e (Maven 2 Eclipse) 1.0, which seems to cause some problems with plugins that are not "known" by m2e. This hits Magnolia with the setproperty Maven plugin and other Maven plugins as well (See list below). If you have m2e 1.0 installed you will likely get the following error upon importing a Maven project (i.e. a Magnolia module) into Eclipse:
| Warning |
|---|
No marketplace entries found to handle Execution currentDate, in /pom.xml in Eclipse. Please see Help for more information. |
Just choose to resolve the issue later and import the project.
Table of plugins which currently do not have a m2e connector
groupId | artifactId | version | goal | execution | phase |
|---|---|---|---|---|---|
org.apache.maven.plugins | maven-javadoc-plugin | 2.8 | javadoc | default | generate-resources |
info.magnolia | maven-setproperty-plugin | 1.1.1 | set-property | currentDate | generate-resources |
org.codehaus.mojo | gwt-maven-plugin | 2.4.0 | resources | default | process-resources |
(Last update April 2012)
Other handy plugins
The following plugins might come in handy. These are not part of the Indigo bundle for now.
Maven Repository
See Maven setup. Be sure to follow these steps first as else you'll not be able to checkout magnolia properly!
Add SVN Repository
You will have to register our SVN repository in case you want to checkout magnolia modules/projects
- open SVN Repository Exploring Perspective
- add repository location
- http://svn.magnolia-cms.com/svn
...
Create/Checkout
...
a
...
Project
...
New
...
Checkout
- open "SVN Repository" perspective (Window -> Open perspective)
- select module/project to check out
- click "Check out as Maven project..."
...
- in
...
- the
...
- context
...
- menu
...

...
Sometimes
...
it
...
is
...
more
...
convenient
...
to
...
checkout
...
a
...
project
...
manually
...
and
...
then
...
use
...
the
...
eclipse
...
import
...
function.
...
This
...
is
...
especially
...
helpful
...
if
...
the
...
module
...
to
...
be
...
imported
...
has
...
submodules.

Setup
...
the
...
Server
...
(Tomcat)
...
Create
...
a
...
Server
...
If
...
not yet done create a server.
Deploy the Webapp project
Open Server Edit Pane
Doubleclick on the server item
Server settings: Disable publishing
Make sure that the option Serve modules without publishing is selected. This ensures that the classes are taken from the target directories.
Server settings: Increase timeouts
In these same settings, increase both timeout values by a factor of 10.
Freemarker specific settings
Taglib definitions (tld)
FreeMarker does not search the classpath to find taglib definition. It uses only WEB-INF/lib and the entries defined in web.xml directly. There are two workarounds:
A) Register taglib definitions in web.xml
- Edit
web.xmland add the taglib definitions as follows. It is important to add them beforejsp-property-group.Code Block xml xml <jsp-config> <taglib> <taglib-uri>cms-taglib</taglib-uri> <taglib-location>cms-taglib.tld</taglib-location> </taglib> <taglib> <taglib-uri>cms-util-taglib</taglib-uri> <taglib-location>cms-util-taglib.tld</taglib-location> </taglib> <taglib> <taglib-uri>cmsfn-taglib</taglib-uri> <taglib-location>cmsfn-taglib.tld</taglib-location> </taglib> <jsp-property-group> <url-pattern>*.jsp</url-pattern> <page-encoding>UTF-8</page-encoding> </jsp-property-group> </jsp-config>

- Copy the files to
webapp/WEB-INF
...
- .
...
B)
...
Put
...
minimal
...
JARs
...
into
...
WEB-INF/lib
...
- In the
webappfolder, execute:Code Block none none mvn war:inplace

Auto completion
Freemarker templates do not provide automatically auto completion of the provided objects.
The provided objects like ctx, stk or mgnl must be declared to the IDE, that they can be auto completed.
There for a configuration file must be provided in each project in your workspace. The file is named '.freemarker-ide.xml'.

Configure Code Style
If you are an internal developer or a contributor please follow the instructions found here: Coding Conventions.
Tips and Tricks
Get the sources or a linked jar / module
- select the jar (in the Maven Dependencies library)
- right click -> Maven -> Download Sources
Dependencies
The dependencies are resolved inside the workspace. This is quite helpful. But this will only work if the version you reference in the project and the version of the module you checked out has the same version. In some cases you will have to adapt the pom files locally (to point to the current snapshot for instance).
Use company wide Java Code Style & Compiler preferences
Simply import the preferences file into your Eclipse.
Known Problems
Wrong maven version is used for dependency checks
If the project can't build because of the following message (printed in Maven Console)

Project contains duplicate entry
Sometimes the same jar is references twice (by maven and EAR dependencies). This sometimes happens if you open eclipse freshly. To make the project compile again you must remove the ear dependency:
- right click project -> Java EE -> Update EAR libraries

depends

the

dependencies

in

apply
...
a
...
combination
...
or

all
...
of

them.
...
Solution
...
1:
...
exclude

the
...
servlet
...
api
...
jar.
...
Verify

servlet
...
api
...
jar
...
in
...
your

dependencies.

dependency
