+### 13.4. Ant
+
+使用Apache Ant+Ivy构建Spring Boot项目是完全可能的。`spring-boot-antlib` AntLib模块能够帮助Ant创建可执行jars，一个传统的用于声明依赖的`ivy.xml`文件可能如下所示：
+```xml
+<ivy-module version="2.0">
+    <info organisation="org.springframework.boot" module="spring-boot-sample-ant" />
+    <configurations>
+        <conf name="compile" description="everything needed to compile this module" />
+        <conf name="runtime" extends="compile" description="everything needed to run this module" />
+    </configurations>
+    <dependencies>
+        <dependency org="org.springframework.boot" name="spring-boot-starter"
+            rev="${spring-boot.version}" conf="compile" />
+    </dependencies>
+</ivy-module>
+```
+同样，一个传统的`build.xml`可能是这样的：
+```xml
+<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="1.3.0.BUILD-SNAPSHOT" />
+
+    <target name="resolve" description="--> retrieve dependencies with ivy">
+        <ivy:retrieve pattern="lib/[conf]/[artifact]-[type]-[revision].[ext]" />
+    </target>
+
+    <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>
+
+    <target name="compile" depends="init" description="compile">
+        <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>
+</project>
+```

+**注** 如果你不想使用`spring-boot-antlib`模块，那查看[Section 81.10, “Build an executable archive from Ant without using spring-boot-antlib”](../IX. ‘How-to’ guides/73.8. Build an executable archive with Ant.md)获取更多指导。
