Install Eclipse (3.5)
Download the Java EE edition which includes WTP (web tool project).
Subversive (Subversion Plugin)
Install the plugin
- Help / Install New Software ..
- select: Galileo - http://download.eclipse.org/releases/galileo
- select: Collaboration/Subversive SVN Team Provider
Note: to get the latest stable version you will better use the project's url. I had to do that because eclipse started to block on startups otherwise.
Connectors
You also have to install a connector. Subversive will prompt you on the first usage.
- open "SVN Repository" perspective (Window -> Open perspective)
- select SVNKit 1.3
- proceed installation

Maven Repository
See Maven setup.
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" in the context menu
Importing an already checked out project from file system
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.
- File -> Import
- in the import dialog select 'Maven Projects'
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
tld's
FreeMarker won't search the classpath for finding the tlds but uses only WEB-INF/lib and the entries defined in web.xml directly. There exist mainly the following two workarounds:
A) register the tlds in web.xml
Edit web.xml and add the taglib definitions as follows. Note it is important to adde them before jsp-property-group
<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>
And copy the files to webapp/WEB-INF
B) put minimal jars into WEB-INF/lib
1. in the webapp folder execute:
mvn war:inplace
2. delete all jars except the taglib jars in src/main/webapp/WEB-INF/lib
3. minimize the taglib jar
zip -d magnolia-taglib-cms-4.1.1-SNAPSHOT.jar /info/* zip -d magnolia-taglib-utility-4.1.1-SNAPSHOT.jar /info/*
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'. I have attached it to this page without the dot at the beginning, or I can't upload it on the Mac otherwise (hidden).
The important part of this configuration file is the declaration of the objects the auto completion should know. I think these four declarations I use make sense:
<value key="mgnl" object-class="info.magnolia.module.templating.MagnoliaTemplatingUtilities"/> <value key="ctx" object-class="info.magnolia.context.MgnlContext"/> <value key="stk" object-class="info.magnolia.module.templatingkit.util.STKUtil"/> <value key="state" object-class="info.magnolia.cms.core.AggregationState"/>
Configure Code Style
If you are an internal developer or a contributor please follow the instructions found here: Code style and Javadoc.
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).
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)
[WARN] Rule 0: org.apache.maven.plugin.enforcer.RequireMavenVersion failed with message: Detected Maven Version: 2.1-SNAPSHOT is not in the allowed range [2.0.9,2.0.9].
The expected stacktrace on startup is:
SEVERE: Exception sending context initialized event to listener instance of class info.magnolia.cms.servlets.MgnlServletContextListener java.lang.NullPointerException at info.magnolia.cms.beans.config.PropertiesInitializer.loadAllModuleProperties(PropertiesInitializer.java:92) at info.magnolia.cms.beans.config.PropertiesInitializer.loadAllProperties(PropertiesInitializer.java:79) at info.magnolia.cms.servlets.MgnlServletContextListener.contextInitialized(MgnlServletContextListener.java:176) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:3843) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4350)
You can either add the following to the pluginManagement section in your main project pom to disable the enforcer plugin or select the eclipse profile:
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-enforcer-plugin</artifactId> <configuration> <skip>true</skip> </configuration> </plugin>
Then clean all projects
To ensure that everything is fine you have to check that magnolia-core/target/classes/mgnl-bean.properties exists.
Freemarker can't find tags (tlds)
See #Freemarkerspecificsettings
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
Class Cast Exception: info.magnolia.cms.filters.MgnlMainFilter
Symptom:
SEVERE: Exception starting filter magnoliaFilterChain java.lang.ClassCastException: info.magnolia.cms.filters.MgnlMainFilter at org.apache.catalina.core.ApplicationFilterConfig.getFilter(ApplicationFilterConfig.java:255) at org.apache.catalina.core.ApplicationFilterConfig.setFilterDef(ApplicationFilterConfig.java:397) at org.apache.catalina.core.ApplicationFilterConfig.<init>(ApplicationFilterConfig.java:108) at org.apache.catalina.core.StandardContext.filterStart(StandardContext.java:3709) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4356) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1045)
Solution: exclude the servlet api jar. Verify that you don't have the servlet api jar in your maven dependencies.
Example:
<dependency> <groupId>info.magnolia</groupId> <artifactId>magnolia-empty-webapp</artifactId> <version>4.0.1</version> <type>pom</type> <exclusions> <exclusion> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> </exclusion> </exclusions> </dependency>
Webapp project doesn't work
- make sure that you have only one webapp project open
- add the pom dependency (not only the war dependency) otherwise the dependencies defined in the referenced war file won't be seen
- use mvn war:inplace to overlay the webapp project (make sure that the WEB-INF/web.xml exists
- ensure that you delete WEB-INF/lib after a war:inplace
Trouble shooting step by step
- check if there are any build issues denoted in the problem view
- check if there are any problems denoted in the pom.xml (missing parents, ..)
- check if the project builds in the terminal (by using mvn only)
- are the parent poms available?
- check the maven log in eclipse (select the maven console in the console view)
- are the logs fine?
- verify that there is no version conflict thrown by the enforcer plugin
- if so configure the project to use the eclipse profile in the project settings (maven tab)
- clean the project
- this ensures that maven is used to build the resources
- verify that the resources have been built (module descriptor in
target/classes/META-INF/magnolia
- update project configuration
- right click project -> maven -> update project configuration
- check the maven console (some errors are not reported to the GUI)
