问题
I am new to ant and Android uiautomator. When using ant to build my testing program I get:
-dex:
[dex] input: c:\Eclipse\workspace\Android\bin\classes
[dex] Converting compiled files and external libraries into c:\Eclipse\wor
kspace\Android\bin\classes.dex...
[dx] no classfiles specified
BUILD FAILED
C:\Android\sdk\tools\ant\uibuild.xml:198: null returned: 1
This is on the sample test code at: http://developer.android.com/tools/testing/testing_ui.html#sample
The full output from running the 'android create uitest...' and 'ant build' commands follows:
c:\Eclipse\workspace\Android>android create uitest-project -n AllAppsTest -t 7 -
p C:\Eclipse\workspace\Android\
Updated file C:\Eclipse\workspace\Android\build.xml
c:\Eclipse\workspace\Android>ant build

My problem is similar to Android ant build project failure which didn't seem to have an answer (or at least one that I could descern from the responses.
I can't post an image (not enough mojo yet) but my test project is set up as:
AllAppsTest
src
com.uia.example.my
LaunchSettings.java
JRE System Library[JavaSE-1.6] (there are number of jar files here but I am not
listing them here)
Referenced Libraries
android.jar
uiautomator.jar
JUnit 4
I executed the following:
c:\Eclipse\workspace\Android>android create uitest-project -n AllAppsTest -t 7 -
p C:\Eclipse\workspace\Android\
Updated file C:\Eclipse\workspace\Android\build.xml
c:\Eclipse\workspace\Android>ant build
Buildfile: c:\Eclipse\workspace\Android\build.xml
Which resulted in the 'ant build' error output at the top of this post.
Any ideas?
Thanks
Eric

Not sure this is kosher answering my own question but...
I believe there is an error in the documentation (or the create step) for executing the build.xml file. The build.xml must be copied to the project directory, in my case AllAppsTest, and the 'ant build' command executed from there.
So the sequence of events to get this to work (in Windows command window):
Run the 'android create' command
c:\Eclipse\workspace\Android>android create uitest-project -n AllAppsTest -t 7 - p C:\Eclipse\workspace\Android\
Switch to the AllAppsTest directory
cd AllAppsTest
Copy the build.xml file from the parent directory
copy ../build.xml
(which for some reason copies local.properties and project.properties also)Run the 'ant build' command
When I first tried this the build failed as it didn't like the single and double quotes I had that were on comment lines. Not sure why that was but I removed them and the ant build worked OK.
