Hi,
I went through setting Eclipse IDE for engine development recently.
After getting the maven build to work, and after importing all projects into eclipse,
following setup is required to get rid of all compilation errors reported by eclipse:
1) at restapi-definition -> project -> properties -> java build path -> source
-> add source folder -> target/generated sources/xjc
2) at webadmin -> project -> properties -> java build path -> source -> add
source folder-> target/generated sources/annotations,gwt,test-annotations
3) To get rid of the error "The method setCharacterEncoding(String) is undefined for
the type HttpServletResponse" in source
frontend/webadmin/modules/frontend/src/main/java/org/ovirt/engine/ui/frontend/server/gwt/WebadminDynamicHostingServlet.java,
I modified pom.xml at root level to change servlet API version from 2.3 to 2.4 as the
concerned API is introduced in 2.4
<javax.ejb.api.version>3.0</javax.ejb.api.version>
- <javax.servlet.api.version>2.3</javax.servlet.api.version>
+ <javax.servlet.api.version>2.4</javax.servlet.api.version>
<jcraft.jsch.version>0.1.42</jcraft.jsch.version>
4) Make sure that you import the engine code formatter into eclipse _before_ starting
development.
Window -> Preferences -> Java -> Code Style -> Formatter -> Import ->
<ovirt-src-root>/config/engine-code-format.xml
5) Above mentioned formatted doesn't work in comments. This can be resolved by adding
"Remove trailing whitespace" in "Save actions" as follows:
Window -> Preferences -> Java -> Editor -> Save Actions -> Additional
Actions -> Configure -> Code Organizing -> Remove trailing whitespace -> All
lines
6) For some reason, editing a properties file in eclipse results in a lot of
"diff" in git, making it difficult to review the code change. So I'm
resorting to editing properties file in a text editor outside eclipse for the time being.
I suspect this may not happen on all machines.
Regards,
Shireesh

Thanks Livnat! The mvn clean was successful. Here are the errors from the
install step:
1. do you have latest? when did you fetch last (I can fetch the same
commit hash to make sure it compiles, I have latest and it compiles)
2. let try to compile the engine without the GWT stub -
$ovirt_engine_home> cd backend/manager
$ovirt_engine_home/backend/manager > mvn install -DskipTests
What is the result of the above?
BTW if you want online help I am on the ovirt IRC channel.
