我应该在java applet样式eclipse项目的.gitignore文件中添加哪些文件和目录？
稍后如果我在不同的计算机上克隆这些项目，我应该能够以最小的努力构建一个eclipse项目。
以下是我项目的目录结构。

./.DS_Store
./.project

可以安全地忽略哪些文件，以便稍后可以在另一台机器上构建这些项目？我可以忽略.jar个文件吗？我found that在Git中使用.classpath和.project是安全的。我的current .gitignore文件包含以下内容。
.DS_Store
doc/
bin/
gen/
build/
*.html
*.log
*.class
