我正在尝试将使用fmpp的ant任务转换为gradle。 我无法构建我的项目。 我的构建.xml文件中有以下内容：
<project name="website">
<property file="build.properties" />
<property name="src.dir" location="src" />
<property name="build.dir" location="build" />
<taskdef name="fmpp" classname="fmpp.tools.AntTask">
<classpath>
<pathelement location="lib/fmpp.jar"/>
</classpath>
</taskdef>
<target name="clean">
<delete dir="${build.dir}" />
</target>
<target name="dist">
<fmpp sourceRoot="${src.dir}" outputRoot="${build.dir}">
<data expandProperties="yes">
base_url: ${base_url}
google_analytics_number: ${google_analytics_number}
mail_user: ${mail_user}
mail_password: ${mail_password}
mail_recipient: ${mail_recipient}
upload_folder: ${upload_folder}
host: ${host}
port: ${port}
</data>
</fmpp>
</target>
</project>
我的build.gradle文件看起来像这样
ant.taskdef(name: 'fmpp', classname:'fmpp.tools.AntTask') {
classpath {
fileset(dir: 'lib', includes: '*.jar')
}
}
ant.fmpp(sourceRoot:"src", outputRoot :"build") {
data(expandProperties: 'yes'){
base_url = base_url
google_analytics_number = google_analytics_number
mail_user = mail_user
mail_password = mail_password
mail_recipient = mail_recipient
upload_folder = upload_folder
host = host
port = port
}
}
但是当我运行它时，我收到以下错误
FMPP 处理会话失败。 原因：freemarker.core.InvalidReferenceException：表达式base_url未定义在第 15 行第 47 列 data/header.htm。
因此，似乎 htm 文件中的模板变量没有在我的构建中正确拾取和实现。 我不知道如何解决这个问题。 fmpp 有一些 gradle 插件，但文档非常有限，我很难让它们中的任何一个工作。 如果有人有建议或解决方法，将不胜感激。
***更新
以下是尝试应用的 htm 文件的示例
<head>

error_reporting(E_ALL);
ini_set('display_errors', 1);
$page = basename($_SERVER['PHP_SELF']);
require_once($_SERVER['DOCUMENT_ROOT'] . '/js/functions.php');

问题在于从gradle.properties读取的属性和数据属性的名称完全相同。要修复它，您需要使用project实例引用隐藏在属性下的值，例如：
base_url = project.base_url
看看我刚刚准备的演示。它运行没有任何错误。如果在gradle.properties中重命名属性，则可以跳过project，这是port2属性的情况 - 故意重命名。
