ant全量/增量打包+環境差別

       下圖是針對性的工程目錄結構,有環境差別env目錄,打包或編譯依賴jar包expandLib目錄,其餘都是Java web工程經常使用目錄。注意ant的打包配置文件存放到工程根目錄下,同時還有2個爲增量打包作準備須要的txt文件changeLog.txt(svn、cvs等項目版本控制提交文件記錄)、patchfiles.txt(加工changeLog.txt文件記錄獲得的最終須要增量打包的編譯文件):html

       解釋說明下ant打包的build.xml配置文件,裏面含有5個環境的增量打包和全量打包,內容都大同小異,讀者本身根據實際狀況,靈活應變,不吝賜教。裏面包含ant腳本不是較經常使用命令,注意ant版本是否包含該命令,有關ant的命令說明詳見官網API。build.xml配置內容具體以下:java

       增長打包,只需將增量文件路徑存放到changeLog.txt,而後執行上面ant增量打包腳本便可。下圖爲實例:web

    
       執行ant增量打包腳本時,須要patchfiles.txt這個臨時文件,將changeLog.txt中文件列表信息進行加工處理以後存放至此,供打包使用。下圖爲其對應實例:
express

       以上信息僅供碼友參考,望靈活使用。若有問題歡迎討論或賜教。
apache
