I am a computer science student learning Java, so I do some work at home and at college on a mixture of Linux and Windows. I have a problem after copying a new project into the Eclipse workspace. The project shows up, but with a red exclamation mark and an error saying:
The project cannot be built until build path errors are resolved
How can I fix this? I tried the solution described here, but it didn't work.

I recommend going to your Problems view, selecting one of the errors, and hitting Ctrl-1 (quick fix). It should offer you the chance to fix all the errors of the selected type, in all files. You can also mouse over the error in the text editor and wait for a popup; it should say "fix 70 other errors of this type".
In Eclipse select the web project and right-click Build Path > Configure Build Path. This will display the Java Build Path window. Add the CICS and Liberty libraries, click Add Library > CICS Liberty libraries > Next > Finish.
For Eclipse you can find the rebuild option under Project > Clean and then select the project you want to clean up... that's all. This will build your project and create a new bin folder.
Identify "project navigator" or "package explorer" view.
Right click on your project, select Build Path --> Configure build Path.
In the emerging window, you will find four tabs, select "Libraries".There, under "Web app libraries" (expand it), you will see the libraries added to the project's classpath. Check if all of them are available. If one or more are not (they'll have "missing" beside their name and a red mark on their icon), check if you need them (perhaps you don't); if you don't need them, remove it, if you need them, exit this window, look out for the missing jar and IMPORT it into your project.
