ant - com.android.ant.NewSetupTask 升级到 SDK v20 工具后未找到错误

Question

升级到 v20 SDK 工具后，我在尝试运行 Ant 构建时收到此错误。

sdk.dir 属性正确且经过验证(添加到 build.xml 中的输出)。解压 anttasks.jar 似乎在最新的工具中确实缺少 NewSetupTask。

去哪儿了？

Answer 1

问题源于我使用的是完全自定义的 build.xml 文件。因此，它包含以下自定义 ant 任务定义:

<taskdef name="setup"
    classname="com.android.ant.NewSetupTask"
    classpathref="android.antlibs" />

<taskdef name="aapt"
    classname="com.android.ant.AaptExecTask"
    classpathref="android.antlibs" />

<taskdef name="aidl"
    classname="com.android.ant.AidlExecTask"
    classpathref="android.antlibs" />

<taskdef name="renderscript"
    classname="com.android.ant.RenderScriptTask"
    classpathref="android.antlibs" />

<taskdef name="dex"
    classname="com.android.ant.DexExecTask"
    classpathref="android.antlibs" />

<taskdef name="apkbuilder"
    classname="com.android.ant.ApkBuilderTask"
    classpathref="android.antlibs" />

<taskdef name="zipalign"
    classname="com.android.ant.ZipAlignTask"
    classpathref="android.antlibs" />

<taskdef name="xpath"
    classname="com.android.ant.XPathTask"
    classpathref="android.antlibs" />

<taskdef name="if"
    classname="com.android.ant.IfElseTask"
    classpathref="android.antlibs" />

anttasks.jar 不再提供其中的一个或多个图书馆。将我的 build.xml 文件与位于 {sdk.dir}/tools/ant/build.xml 的文件进行比较我注意到这些定义已被替换为以下内容:

<taskdef resource="anttasks.properties" classpathref="android.antlibs" />

替换旧的任务定义。在我的 build.xml 文件中，这个新的任务 def 语句删除了对丢失任务的引用并解决了我的问题。
