我正在使用 eclipse ide 来构建 apk 文件。现在我想在 linux 的命令行中创建 apk 文件。但是当我说 ant debug 时，它给出了以下错误：
Unable to obtain resource from anttasks.jar
java.util.zip.ZipException : error in opening zip file
Problem : failed to create task or type checkenv
Cause : The name is undefined
Action : Check the spelling
Action : Check that any custom tasks/types have been declared
Action : Check that any <presetdef>/<macrodef> declarations have taken place
I have ant version 1.9.2 . and android version 17. I have build.xml file .

Use this example
You need to pass sdk.dirinto ant, i.e. ant -Dsdk.dir=<path to Android SDK>
使用这个例子你需要传入sdk.dirant，即ant -Dsdk.dir=<path to Android SDK>
You'll also need to specify one of the seven or so Android build targets because the default build target is 'help'.
您还需要指定七个左右的 Android 构建目标之一，因为默认构建目标是“帮助”。
If you just run ant -Dsdk.dir=<path to Android SDK>, you'll get some help output, like so:
如果你只是运行ant -Dsdk.dir=<path to Android SDK>，你会得到一些帮助输出，像这样：
help:
[echo] Android Ant Build. Available targets:
[echo] help: Displays this help.
[echo] clean: Removes output files created by other targets.
[echo] compile: Compiles project's .java files into .class files.
[echo] debug: Builds the application and signs it with a debug key.
[echo] release: Builds the application. The generated apk file must be
[echo] signed before it is published.
[echo] install: Installs/reinstalls the debug package onto a running
[echo] emulator or device.
[echo] If the application was previously installed, the
[echo] signatures must match.
[echo] uninstall: Uninstalls the application from a running emulator or
[echo] device.
BUILD SUCCESSFUL Total time: 7 seconds To build the APK, you have to specify debug or release.
BUILD SUCCESSFUL 总时间：7 秒 要构建 APK，您必须指定 debug 或 release。
ant -Dsdk.dir=<path to Android SDK> debug
This will help you creating an apk file
这将帮助您创建一个 apk 文件

Be sure that you have a file named local.propertiesin the root directory (i.e. same directory as your build.xml).
确保您local.properties在根目录（即与您的 相同的目录build.xml）中有一个文件。
Be sure that this file contains a line like this:
确保该文件包含如下一行：
sdk.dir=c:\tools\android-sdk
(Of course you need to adapt the path to your effective sdk location)
（当然你需要调整路径到你的有效sdk位置）
Double-check that the path is correct.
仔细检查路径是否正确。
Re-run ant debug
重新运行 ant debug
Note : the file local.properties is local (and is usually not under version control !)
注意：文件 local.properties 是本地的（通常不受版本控制！）
