使用NERDTree插件作为默认目录树:
修改autoload/eclim/project/tree.vim

定位在第107行:

    "call eclim#project#tree#ProjectTreeClose()
    "call eclimd#project#tree#ProjectTreeOpen(display,names,dirs)
    exec(":NERDTree ".dir)
endfunction " }}}

当打开项目后自动CD到项目目录:
修改autoload/eclim/project/tree.vim

定位在第108行:

    "call eclim#project#tree#ProjectTreeClose()
    "call eclimd#project#tree#ProjectTreeOpen(display,names,dirs)
    exec(":NERDTree ".dir)
    exec(":cd ".dir)
endfunction " }}}
