Code quality:
It is used to enforce Coding Standards in Java Project, such as Naming conventions, Coding problems, Best Practices.

PMD focuses more on preemptive defect detection.

FindBugs concentrates on detecting potential bugs and performance issues.
Klocwork is aimed at improving software security, quality, and reliability. It is not free, but we can get 30 days free trail. And it is really very cool.

Mylyn can integrate with issue management systems such as Bugzilla, and it also provides context management, which can hide much of the detail of projects that is irrelevant to the task at hand.
Mylyn is very helpful, especially your main job is to fix defects, or focus on one component of a big project.

EPIC - Perl Editor and IDE for Eclipse
The PyDev Update Site
Groovy Eclipse plugin
Aptana Studio

Recently, I re-downloaded and reinstalled jdk, and Eclipse always shows this error:
'UnsupportedEncodingException: GBK'. After google search, on,
I found out this is because I installed a JRE only for US English, and I should choose to download and install Multi-language JRE.

When we save file, it may print out the error "Some characters can not be mapped using GBK character encoding".
The solution is to change file encoding to 'utf-8':
Select Window -> Preferences ->General
Select  Workspace , set Text file encoding to 'utf-8'.
Select Content Types, set Default encoding to 'utf-8'

Ignore white space when compare two files in Eclipse IDE
When compare two files in Eclipse, many times lines differ only in white spaces, and we don't want to notice this minor difference.
Select Window -> Preference -> Compare/Path, and in 'General' tab, select the checkbox --'Ignore white space'.
