Counting Line Numbers in Eclipse
提问by user128807
I have a Java project in Eclipse with ~10 packages and ~10 class files per package. Is there a way to determine total lines of code for the whole project from within Eclipse? I am familiar with other tools (e.g., Code Analyzer, wc, etc.) but I want to know if there is a way to do this within Eclipse (or get confirmation that there is no way to do it).
我在 Eclipse 中有一个 Java 项目，每个包有 ~10 个包和 ~10 个类文件。有没有办法从 Eclipse 中确定整个项目的总代码行数？我熟悉其他工具（例如，代码分析器、wc 等），但我想知道是否有办法在 Eclipse 中执行此操作（或确认无法执行此操作）。

Here's a good metrics plugin that displays number of lines of code and much more:
这是一个很好的指标插件，可以显示代码行数等等：

It says it requires Eclipse 3.1, although I imagine they mean 3.1+
它说它需要 Eclipse 3.1，虽然我想他们的意思是 3.1+
Here's another metrics plugin that's been tested on Ganymede:

I think if you have MyEclipse, it adds a label to the Project Properties page which contains the total number of source code lines. Might not help you as MyEclipse is not free though.
我想如果你有 MyEclipse，它会向包含源代码行总数的项目属性页面添加一个标签。可能对您没有帮助，因为 MyEclipse 不是免费的。
Unfortunately, that wasn't enough in my case so I wrote a source analyzer to gather statistics not gathered by other solutions (for example the metrics mentioned by AlbertoPL).
不幸的是，这对我来说还不够，所以我编写了一个源分析器来收集其他解决方案没有收集的统计数据（例如 AlbertoPL 提到的指标）。

Are you interested in counting the executable lines rather than the total file line count? If so you could try a code coverage tool such as EclEmma. As a side effect of the code coverage stats you get stats on the number of executable lines and blocks (and methods and classes). These are rolled up from the method level upwards, so you can see line counts for the packages, source roots and projects as well.
您是否对计算可执行行数而不是总文件行数感兴趣？如果是这样，您可以尝试使用代码覆盖工具，例如EclEmma。作为代码覆盖率统计的副作用，您可以获得有关可执行行和块（以及方法和类）数量的统计数据。这些是从方法级别向上汇总的，因此您还可以查看包、源代码根和项目的行数。

Check the Regular expressionbox.
选中该Regular expression框。
Use this expression:
使用这个表达式：
\n[\s]*
\n[\s]*
Select whatever file types (*.java, *.xml, etc..) and working sets are appropriate for you.
选择适合您的任何文件类型（*.java、*.xml等）和工作集。

You could use former Instantiations product CodePro AnalytiX. This eclipse plugin provides you suchlike statistics in code metrics view. This is provided by Google free of charge.
您可以使用以前的 Instantiations 产品CodePro AnalytiX。这个 eclipse 插件在代码度量视图中为您提供了类似的统计信息。这是由 Google 免费提供的。

Under linux, the simpler is:
在linux下，更简单的是：
- go to the root folder of your project
- use
findto do a recursive search of *.java files - use
wc -lto count lines:
- 转到项目的根文件夹
- 用于
find对 *.java 文件进行递归搜索 - 用于
wc -l计算行数：
To resume, just do:
要恢复，只需执行以下操作：
find . -name '*.java' | xargs wc -l

You could use a batch file with the following script:
您可以使用带有以下脚本的批处理文件：
@echo off
SET count=1
FOR /f "tokens=*" %%G IN ('dir "%CD%\src\*.java" /b /s') DO (type "%%G") >> lines.txt
SET count=1
FOR /f "tokens=*" %%G IN ('type lines.txt') DO (set /a lines+=1)
echo Your Project has currently totaled %lines% lines of code.
del lines.txt
PAUSE
