Java/Ant/Property File

Define property file through url

<?xml version="1.0"?>
<project name="Apache Ant Properties Project" default="properties.url" basedir=".">

  <target name="properties.url">
    <property url="http://localhost:8080/antBook/properties/build.properties"/>
    <path id="build.classpath.id">
      <pathelement path="${build.classpath}"/>
    </path>
    <property name="build.classpath.property" refid="build.classpath.id"/>
    <echo message="Server URL: ${server.url}"/>
    <echo message="Build classpath: ${build.classpath}"/>
    <echo message="Build classpath converted: ${build.classpath.property}"/>
  </target>
</project>

Use separate property file

<?xml version="1.0"?>
<project name="Apache Ant Properties Project" default="properties.localfile" basedir=".">

  <target name="properties.localfile">
    <property file="build.start.properties"/>
    
    <path id="build.classpath.id">
      <pathelement path="${build.classpath}"/>
    </path>
    <property name="build.classpath.property" refid="build.classpath.id"/>
    <echo message="Server URL: ${server.url}"/>
    <echo message="Build classpath: ${build.classpath}"/>
    <echo message="Build classpath converted: ${build.classpath.property}"/>
  </target>


</project>
