在build.xml中使用if语句给出错误

Question

我通过詹金斯运行一个项目，但我因为

/var/lib/jenkins/workspace/K2_Learning_Build/build.xml:130: The following error occurred while      
executing this line:

/var/lib/jenkins/workspace/K2_Learning_Build/IgnitorACE/build.xml:251: Element type "if" must be  
followed by either attribute specifications, ">" or "/>".

我已经在build.xml中使用if条件，如下所示，位于第251行

<if ${INSTITUTE_NAME} == "K2_Learning">
<property name = "https.start" value='android:htps=\"' />
<replaceregexp file="../BuildConfig/src/com/edutor/build/${TYPE}.java"  match="public static     
 final String NAVIGATION_MENU_ITEMS[] = (.*)"  replace="public static final String 
 NAVIGATION_MENU_ITEMS[] = ${MENU_LIST_ITEMS};" />    
</if>
<else>
<echo>INSTITUTE_Name: ${INSTITUTE_NAME}</echo>
</else>

请提出解决方案...

Answer 1

据我所知， if这样，您将无法使用...试试：

<if>
    <contains string="${INSTITUTE_NAME}" substring="K2_Learning" />
    <then>
        ...
    </then>
</if>

另请参见SF的规范和示例： ant-contrib（如果有规范）
