Is there something that explains how to configure a clean installation of
Eclipse (4.2/Juno) to enable Maven features to recognize, build, deploy and
debug an existing maven web application or service? I've looked through
http://wiki.eclipse.org/M2E <http://wiki.eclipse.org/M2E> and related
pages but I couldn't find a complete explanation of the process.
I downloaded the latest 4.2.0 Juno J2EE installer
(eclipse-jee-juno-installer-windows.exe) from Genuitec and installed the
64-bit version.
I then pulled all updates and have installed the following as listed in the
"Software and Workspace Center" view:
- TestNG (6.7.0)
- Maven Integration (m2e) (2 related) (1.1.0)
- Microsoft Visual Studio Team Foundation Server plug-in for Eclipse
(11.0.0)
- Eclipse EGit (2.1.0)
- EGit Plug-in Import Support (2.1.0)
- EGIT Mylyn (2.1.0)
- EGIT Project Set Support (2.1.0)
- Eclipse Java Web Development Core (3.4.1)
- Eclipse Java Web Developer Tools (3.4.1)
- Eclipse Java Web Developer Tools User Documentation (3.4.1)
- Web Page Editor (2.3.8)
- JAX-WS DOM Tools (1.0.200)
- JAX-WS Tools (1.2.0)
- m2e - Maven Integration for Eclipse (1.2.0)
- m2e - slf4j over logback logging (Optional) (1.2.0)
- Subclipse 1.8.x (5 related) (1.8.16)
- Mylyn Versions Connector: Git (1.0.1)
- JavaScript Development Tools (1.4.1)
- WST Web Core (3.4.1)
- Eclipse Web Developer Tools (3.4.1)
- WST Web User Documentation (3.3.0)
- WST Web Services Core (3.4.0)
- Web Services Tools (3.4.1)
- WST Web Services User Documentation (3.4.1)
I deleted all existing source folders, then used the Microsoft Team
Explorer Everywhere plugin to get latest application source.
Next, I go to Import->Maven->"Existing Maven Projects". The project shows
up, but doesn't appear to be recognized as a web application. I right
click, go to Debug As-> or Run As-> but there is no Run on server option.
I then go to <Project>->Properties->Project Facets->Convert to Faceted
form... (should I really have to do this manually?) and select the
following:
- Dynamic Web Module (v2.5)
- Click "Further configuration available..."
- change content directory from "WebContent" to*
src/main/webapp*(Maven 'convention' but not what m2e/Eclipse seems to
want -- see below)
- UNCHECK Generate web.xml deployment descriptor (Already exists
in my project)
- Change Java from v1.7 to v1.6
- Click OK
Now I see a "JAX-WS Web Services" node in the project, even though it isn't
a JAX-WS Web service (not sure if that means anything) but I can now
initiate a "Run On Server" or "Debug On Server" from the menus...yay!
However, doing "Run as->Run On Server" and selecting my Tomcat 6 server
seems to deploy, but nothing happens...boo! It didn't even say it was
starting the application even though it deployed according to tomcat.
After a few more hours of searching, someone listed an example with the
"Content directory" as "target/<webappfolder>", presumably where the
assembled web app is located after a build.
That seemed to work. However, my Maven project builds the war and names
the "target/<webappfolder>" with the Maven version as part of the folder
name (e.g., WebApp-1.0.1-SNAPSHOT) so if I release and/or change the
version, it breaks and I can't find a way to change this folder location
once it is set!!! Shouldn't the "content directory" be dynamic based on
the POM?
*Questions:*
1. *Am I doing this right?*
2. *Why doesn't m2e (or eclipse?) infer the src and/or target
information it needs from the POM and content instead of me having to hold
it's hand?*
3. *Can I change the "content directory" after it is set the first time?
If so, how?*
4. *Does it really have to be this hard to import an existing maven
project?*
Thanks!
