在ant中引用外部.jar库以构建Android Java jar

Question

(I am new to ant and I've scoured the web for solutions to this, but none of them seem to work for me.)

I am trying to reference an external .jar library in building with ant. But, I receive errors such as: package [name] does not exist , next to the import [name] statement in the .java file

In my build.xml, I have the following line, which references the folder where the external jar is stored:

<property name="lib.dir" value="libs"/>

When I remove references to the external jar, ant builds. Right now, it just seems like ant is unable to find the external libraries, and

如果需要编译中包含的jar，可以执行以下操作：

<javac srcdir="${src.dir}" destdir="${local.build.dir}" source="1.5" target="1.5" classpathref="base.classpath" debug="true">

Try removing this property entry and rebuilding. I have always had external library jars and it is always sufficient to add them in libs folder to get everything building successfully.

The reason why this property entry might be failing you is: the auto-generated build.xml references another build file in the android sdk tools folder. This other build file knows how to reference the libs folder of the project you are currently building, but from its perspective the path is not simply libs .
