要声明依赖，可参考以下一个典型的 ivy.xml 文件内容：

<project
    xmlns:ivy="antlib:org.apache.ivy.ant"
    xmlns:spring-boot="antlib:org.springframework.boot.ant"
    name="myapp" default="build">
    <property name="spring-boot.version" value="2.0.0.RELEASE" />
    <target name="resolve" description="--> retrieve dependencies with ivy">
        <ivy:retrieve pattern="lib/[conf]/[artifact]-[type]-[revision].[ext]" />
    <target name="classpaths" depends="resolve">
        <path id="compile.classpath">
            <fileset dir="lib/compile" includes="*.jar" />
        </path>
    </target>
    <target name="init" depends="classpaths">
        <mkdir dir="build/classes" />
    </target>
        <javac srcdir="src/main/java" destdir="build/classes" classpathref="compile.classpath" />
    </target>
    <target name="build" depends="compile">
        <spring-boot:exejar destfile="build/myapp.jar" classes="build/classes">
            <spring-boot:lib>
                <fileset dir="lib/runtime" />
            </spring-boot:lib>
        </spring-boot:exejar>
    </target>
