Building carrot2 source code in Java - eclipse

I'm trying to compile Carrot2 code in Eclipse but I'm getting a lot of warnings:
.apt_generated/ is missing from source..
etc
Do you have any idea please?

Which version of Eclipse are you using? Did you follow the steps to set up your project outlined here? http://download.carrot2.org/head/manual/index.html#section.integration.setting-up-carrot2-sources-in-eclipse

The import org.apache.commons.net cannot be resolved - Eclipse Juno

Good morning:
I have a terrible problem with my Eclipse Juno.
Due to I had to format my computer, I lost the configuration of my Eclipse Juno.
I am trying to work again with my new Eclipse Juno configured, but I think something is missing.
My problem is, I import a Java Project that HAS NO ERROR some weeks ago, and I am 100 % sure about that.
Now, the project has errors like:
**The import javax.mail cannot be resolver
The import org.apache.commons.net cannot be resolved
TimeStamp cannot be resolver to a type
**
Of course, I tried all.
I cleaned the project.
I tried to remove and add again all the libraries I got in the java build path.
I tried to switch from jre6 to jre7.
I tried to change the Target Platform...
Nothing worked!! I am desperate!
Can anyone help me?
PS: I have the tomcat 5.5 installed in Eclipse Juno also.
Thank you.
Calm yourself. The problem is simply that your project need some additional libraries to be compiled. By the errors you showed, you need at least these:
javamail.jar
commons-net.jar
They are both open source libraries and you will find them with a bit of googling.
Why before formatting everything worked fine, and now it doesn't anymore? Surely you had these libraries in some other place outside your project. For example, within the bundled libraries of Tomcat.

can not create c++ project using NetBeans IDE, build host not connected

I'm new to C++ and is trying to use the NetBeans IDE to create a C++ project. However, I have encountered the following error. I have downloaded the sygwin compiler but after mending around for a hour and half, I still couldn't get the NetBeans C++ compiler working? Could someone please give me a hand? I apologise if this sounds silly to some of you. Thanks in advance for any help!
The NetBeans C/C++ bundle does not include a C/C++ compiler.
You have to download an environment like Cygwin or MinGW which includes the compiler and then add it as build host.

Dagger setup in Eclipse

I'm having trouble setting up an Eclipse project for the Coffee example in the Dagger repo.
Below are screenshots of the error message and the Eclipse settings I'm using. Any suggestions would be greatly appreciated.
Thanks.
Looks like your version of Javawriter should be 2.2.1

Scala Eclipse IDE - strange behavior

I am giving a try to Scala Eclipse IDE after a very long time. I installed Eclipse and the said Scala plugin only a while ago, but I am unable to get stuff working. In all of the Scala files, I get the errors like following (See the tooltip):
This project uses Gradle for building, and I also have the latest version of Groovy plugin installed. Please help me get this thing working. Thanks.
Edit:
Thank you, everyone. The problem was solved. It appears there was a problem with my Scala plugin installation. A complete reinstall of everything (including Eclipse) helped. Also, this time I did not install the Groovy plugin.
I don't know which version of Eclipse / Scala-IDE you're using, but there are two reasons I know this sometimes happens:
1) You don't have JDT weaving for Scala installed.
The scala-ide uses aspects to weave in code into the JDT compiler. If you don't have this installed, this may cause the Scala files to be seen as Java files.
2) If, somehow, the Java Source File content type includes *.scala. In fact, it should be Scala Source File. If this is the case, you should remove the *.scala from the Java Source File content type.
