Adding referenced jars to android build.xml

Question

I have an android eclipse project and have generated the corresponding build.xml ant file by doing:

android update test-project -p . -m ..\main_project

This compiles fine. However, in eclipse I have then added three referenced external jars (easymock, objenesis and cglib). In eclipse everything builds fine but then when I run the above command again it doesn't add these jars to the classpath.

So my question is how to tell the build.xml to include these jars?

I have done some research first and some people suggested changing the rules files in the sdk itself but this is something I want to avoid as then everyone in my team would need to do this and that's not practical.

Thanks Stephen

You can add jars to java classpath for android using eclipse as follows Right click on project > properties > Java Build path > Add External Jars. — Ashwin N Bhanushali, Oct 11 '11 at 08:27

Hi, I added them successfully to the eclipse project and there is no problem. What I need to get working is the ant build.xml files for automation. — steprobe, Oct 11 '11 at 08:48

add jar.libs.dir=your_path_here/lib in ant.properties for SDK >=8

... or your_path_here/libs which is the default for SDK 13. See the jar.libs.dir property in $SDK_DIR/tools/ant/build.xml. – Scott C Wilson Mar 29 '12 at 21:37
is this mandatory to have a sub folder named lib/ or libs/ in my custom lib directory. Should the path be relative to the build.xml file at the root of my project, or absolute ? – svassr Feb 12 '14 at 22:27

For build.xml you can set property "external.libs.dir" in one of your properties file( like build.properties), by default it points to libs/ folder of your project - simply put there all your jars

external.libs.dir=<your_custom_path>/lib

`external.libs.dir` does not work for newer version, use the taranfx answer instead – FxIII Dec 15 '11 at 11:42
Yes, they extensively changing ant scripting to separate out libraries as standalone components – acm0x Dec 15 '11 at 12:20
See @geeknizer answer below for SDK 13. – Scott C Wilson Mar 29 '12 at 21:38

You should ideally use libs/ not lib, to remain consistent with Eclipse.

Joe Malin is correct. libs/ is recommended by the android documentation. http://tools.android.com/recent/dealingwithdependenciesinandroidprojects – Mark F Guerra Mar 14 '13 at 19:18
