13.4 Ant

使用Apache Ant+Ivy构建Spring Boot项目是可行的.spring-boot-antlib AntLib模块可以用来帮助Ant创建可执行的jar. 声明依赖关系，典型的ivy.xml文件看起来如下例子所示:

  1. <ivy-module version="2.0">
  2. 　　<info organisation="org.springframework.boot" module="spring-boot-sample-ant" />
  3. 　　<configurations>
  4. 　　　　<conf name="compile" description="everything needed to compile this module" />
  5. 　　　　<conf name="runtime" extends="compile" description="everything needed to run this module" />
  6. </configurations>
  7. 　　<dependencies>
  8. 　　　　<dependency org="org.springframework.boot" name="spring-boot-starter"
  9. 　　　　rev="${spring-boot.version}" conf="compile" />
  10. 　　</dependencies>
  11. </ivy-module>

典型的build.xml文件看起来如下例子所示:

  1. <project
  2.   xmlns:ivy="antlib:org.apache.ivy.ant"
  3.   xmlns:spring-boot="antlib:org.springframework.boot.ant"
  4.   name="myapp" default="build">
  6.   <property name="spring-boot.version" value="2.0.2.RELEASE" />
  8.   <target name="resolve" description="--> retrieve dependencies with ivy">
  9.     <ivy:retrieve pattern="lib/[conf]/[artifact]-[type]-[revision].[ext]" />
  10.   </target>
  12.   <target name="classpaths" depends="resolve">
  13.     <path id="compile.classpath">
  14.       <fileset dir="lib/compile" includes="*.jar" />
  15.     </path>
  16.   </target>
  18.   <target name="init" depends="classpaths">
  19.     <mkdir dir="build/classes" />
  20.   </target>
  22.   <target name="compile" depends="init" description="compile">
  23.     <javac srcdir="src/main/java" destdir="build/classes" classpathref="compile.classpath" />
  24.   </target>
  26.   <target name="build" depends="compile">
  27.     <spring-boot:exejar destfile="build/myapp.jar" classes="build/classes">
  28.       <spring-boot:lib>
  29.         <fileset dir="lib/runtime" />
  30.       </spring-boot:lib>
  31.     </spring-boot:exejar>
  32.   </target>
  33. </project>

Tip

如果你不想使用spring-boot-antlib模块,请参考Section 86.9 Build an Executable Archive from Ant without Using spring-boot-antlib
