openfire(一)：使用idea编译openfire4.2.3

1.下载源码

http://www.igniterealtime.org/downloads/source.jsp

2.使用idea导入源码

File-New-Project from Existing Sources 导入解压后的源码

一路next

导入后的目录结构如下

设置Project SDK

打开File-Project Structure（本人使用的jdk1.8）

3.使用ant编译源码

　　a)打开右侧ant build菜单，点击+号，选择openfire-src-build下的build.xml文件

　　b)点击ant build菜单蓝色按钮（第四个）过滤

　　c)选择openfire后点击run按钮（第三个）

4.配置运行参数

　　a)选择application

　　b)设置一些启动参数如图所示

　　c)启动（此步会报一些错）

Q:Error:java: 无效的源发行版: 1.9

A：此处选择8

 Q：Error:(571, 21) java: 无法访问org.apache.tools.ant.Task

　　找不到org.apache.tools.ant.Task的类文件

A:缺少ant包

 　　 1.将idea路径下或者自己下载的ant.jar复制到openfire_src>build->ib>ant目录和openfire_src>build->ib>merge目录下

   　   2.打开project structure，选择libraries下的ant和merge，将刚才的ant.jar添加进去

　　   3.选择project structure-modules-tools模块，加入ant依赖

 Q:启动成功，打开控制台页面报

HTTP ERROR 404

Problem accessing /login.jsp. Reason:

    /login.jsp

Powered by Jetty://

A:在web>WEB-INF>web.xml中添加

<jsp-config>
    <taglib>
        <taglib-uri>admin</taglib-uri>
        <taglib-location>/WEB-INF/admin.tld</taglib-location>
    </taglib>
</jsp-config>
然后使用ant重新编译后启动

Q:再次启动后报500错误

HTTP ERROR 500

A:缺少配置文件
　　1.将D:\IntelliJ IDEA 2017.3.3\workspace\openfire_src\src\resources\jar下的admin-sidebar.xml复制到D:\IntelliJ IDEA 2017.3.3\workspace\openfire_src\out\production\openfire_src
　　2.将D:\IntelliJ IDEA 2017.3.3\workspace\openfire_src\src\i18n下的所有文件复制到D:\IntelliJ IDEA 2017.3.3\workspace\openfire_src\out\production\openfire_src

成功进入控制台
