我们已经修改了我们的 android ant 构建。build.xml 文件现在如下所示:
<?xml version="1.0" encoding="UTF-8"?>
<!-- This is a modified version of the "dex-helper" macro. It added the "input-dir" and
"output-dex-file" required attributes.
Configurable macro, which allows to pass as parameters input directory,
output directory, output dex filename and external libraries to dex (optional) -->
<macrodef name="dex-helper-mod">
<attribute name="input-dir" />
<attribute name="output-dex-file" />
<element name="external-libs" optional="yes" />
<element name="extra-parameters" optional="yes" />
<attribute name="nolocals" default="false" />
<sequential>
<property name="out.dex.input.absolute.dir" value="${out.classes.absolute.dir}" />
<!-- set the secondary dx input: the project (and library) jar files

<if>
<condition>
<isreference refid="out.dex.jar.input.ref" />
</condition>
<else>
<path id="out.dex.jar.input.ref">

</sequential>
</macrodef>
<!-- This is a modified version of "-dex" target taken from $SDK/tools/ant/main_rules.xml -->
<!-- Converts this project's .class files into .dex files -->
<target name="-dex" depends="-compile, -post-compile, -obfuscate" unless="do.not.compile">
<if condition="${manifest.hasCode}">

</then>
<else>
<echo>hasCode = false. Skipping...</echo>

<!-- version-tag: custom -->
<import file="${sdk.dir}/tools/ant/build.xml" />
现在我们将构建逻辑迁移到 gradle。是否可以像上面那样修改 gradle build ?
