Maven options
To build camel maven has to be configured to use more memory

Using an IDE
If you prefer to use an IDE then you can auto-generate the IDE's project files using maven plugins. e.g.
IntelliJ

mvn idea:idea

Eclipse
There are several ways to import the projects into Eclipse.
m2e
Starting with Camel 2.14.0, Camel can be imported into Eclipse using m2e Maven integration.
Before you start: It is important to run Eclipse with at least 1.5 GB of heap memory, otherwise the import process will fail. To increase the heap size, edit the "eclipse.ini" file and set the -Xmx parameter as follows:
Code Block | ||
---|---|---|
| ||
[...]
-Xmx1536m |
Cloning the Git Repository
Either follow instructions about getting the latest source, or clone the Git repository with Eclipse by selecting "File -> Import -> Git / Projects from Git" and "Clone URI". Provide all repository details in the import wizard and clone the repository into a directory outside of the Eclipse workspace. Once cloning has completed, exit the import project wizard (i.e. simply select cancel when asked to select "Wizard for project import").
Import Maven Projects
Import Camel projects as Maven projects using m2e by selecting "File -> Import -> Maven -> Existing Maven Projects". Point the wizard to the root directory of the cloned repository. Eclipse will analyze all Camel projects and eventually present the following summary:
Simply confirm the import of all projects by clicking "Finish". The import process will create Eclipse projects and automatically set up build paths using dependency details provided by the pom.xml files. Once completed, all Camel projects will be available in your workspace:
maven-eclipse-plugin
The maven-eclipse-plugin can be used to generate the .classpath/.project/.settings file that Eclipse need. To do this, run:
Code Block | ||
---|---|---|
| ||
mvn process-test-sources eclipse:eclipse
|
or
Code Block | ||
---|---|---|
| ||
mvn -Psetup.eclipse -Declipse.workspace.dir=/path/to/your/workspace
|
The latter is recommended as it would completely setup the workspace for you as well as provide options to wire in other projects also found in your workspace.
After running the above command, from within Eclipse, do "File -> Import -> Existing Projects into Workspace", select the root camel checkout location and Eclipse should find all the projects.
Adding Camel Eclipse templates to your workspace
The above mentioned setup.eclipse profile does a few additional things to your workspace:
- Adds the Camel code templates (see here)
- Sets the M2_REPO variable in the workspace that points to your local Maven repository (i.e.,
~/.m2/repository
on Unix andc:\Documents and Settings\<user>\.m2\repository
on Windows) which allows the jars to be resolved.
Hint: specify the workspace location in your .m2/settings.xml
You can add a profile to your .m2/settings.xml to specify your eclipse workspace location so you can avoid having to type that each time you need to update the projects.
...
<profiles>
<profile>
<id>setup.eclipse</id>
<properties>
<eclipse.workspace>/path/to/your/workspace</eclipse.workspace>
</properties>
</profile>
</profiles>
Building with checkstyle
To enable source style checking with checkstyle, build Camel with the -Psourcecheck parameter

mvn -Psourcecheck clean install

Building source jars
If you want to build jar files with the source code, that for instance Eclipse can important so you can debug the Camel code as well. Then you can run this command from the camel root folder:
