Eclipse count lines of code [closed]

There's always the "brute force":

1. Search->File

2. Type the following in "Containing text" -> ^.*$. Then check the "Regular Expression" checkbox

3. Type the following in "File name patterns" -> *.java

4. Click "Search"

5. Check the number of matches in the "Search" Tab.

Install the Eclipse Metrics Plugin. To create a HTML report (with optional XML and CSV) right-click a project -> Export -> Other -> Metrics.

You can adjust the Lines of Code metrics by ignoring blank and comment-only lines or exclude Javadoc if you want. To do this check the tab at Preferences -> Metrics -> LoC.

That's it. There is no special option to exclude curly braces {}.

The plugin offers an alternative metric to LoC called Number of Statements. This is what the author has to say about it:

This metric represents the number of statements in a method. I consider it a more robust measure than Lines of Code since the latter is fragile with respect to different formatting conventions.

Edit:

After you clarified your question, I understand that you need a view for real-time metrics violations, like compiler warnings or errors. You also need a reporting functionality to create reports for your boss. The plugin I described above is for reporting because you have to export the metrics when you want to see them.

If on OSX or *NIX use

Get all actual lines of java code from *.java files

find . -name "*.java" -exec grep "[a-zA-Z0-9{}]" {} \; | wc -l

Get all lines from the *.java files, which includes empty lines and comments

find . -name "*.java" -exec cat | wc -l

Get information per File, this will give you [ path to file + "," + number of lines ]

find . -name "*.java" -exec wc -l {} \;

One possible way to count lines of code in Eclipse:

using the Search / File... menu, select File Search tab, specify \n[\s]* for Containing text (this will not count empty lines), and tick Regular expression.

Another way would by to use another loc utility, like LocMetrics for instance.
It also lists many other loc tools. The integration with Eclipse wouldn't be always there (as it would be with Metrics2, which you can check out because it is a more recent version than Metrics), but at least those tools can reason in term of logical lines (computed by summing the terminal semicolons and terminal curly braces).
You can also check with eclipse-metrics is more adapted to what you expect.
