I'm having problems with a java.lang.NoClassDefFoundError when trying to run my JUnit tests from ANT using the runtestsreport task in thefollowing build.xml; I know the other tasks work, it's just the actual running of the tests that's the problem.
I've tried lots of adjustments based on questions posted on here but I can't fix it; what I really need is a dev to pair with but they've all gone home for the day.
Can anyone help?
The build.xml file is

Any eyes over this to help me get the tests running would be greatly appreciated.
Thanks

Update
I observe that if I edit tests.classpath to remove the following 2 lines then the error I see switches to a ClassNotFound which makes sense as it has no references to the .jar files that contain the classes.
<fileset dir="${testsbuild}/jar" includes="**/*.jar"/>
<fileset dir="${frameworkbuild}/jar" includes="**/*.jar"/>
With the above 2 lines present in the tests.classpath is happily finds them but with the wrong name and it's that error I don't know how to fix.
Problem caused by the following jar command:
<jar destfile="${testsbuild}/jar/tests.jar" basedir="${testsbuild}" />
The testsbuild property should be set to
<property name="testsbuild" location="C:\<path on my machine>\workspace\ESS\build"/>
Explanation
The file Credentials.class was compiled as the class esstestapp.tests.Credentials. It needs to be found on the classpath as the file:
esstestapp/tests/Credentials.class

I am trying to compile a class named TestsVorgabe wich represents a testsuite including five other tests. It works fine with normal JUnit testing, but when i try to compile it with ant i get an
error: cannot find symbol
Project structure like this:
project/src => Classes
project/test => TestClasses
To make sure i really get the correct .jars and include them i have two ways delivering them to Ant. My Ant Buildfile looks like this:
<property name="src.dir" location="src"/>
<property name="build.dir" location="build"/>
<property name="dist.dir" location="dist"/>

I have tried many ways to inculde the .jars and many ways of compiling the tests, but nothing seemed to work so i ended up with this (do not work too).
You compile your sources with javac into the ${build.dir} but you doesn't add that to the classpath of the junit task, this is an example from the documentation:
<classpath>
<pathelement location="${build.tests}"/>
<pathelement path="${java.class.path}"/>
</classpath>
Or check this example(in the example: ${web.classes.dir}).
Try to add build.dir to the junit task classpath, I hope this helps!
I have junit tests that use selenium to test web server.
When i run the tests using ant from command line, everything is working fine, browser gets opened and tests are going as planed.Browser gets open and i can see tests running.
Recently ive tried to add automatic tests as part of Ci cycle running on jenkins.
I run it as ant build command.
I can see that ant is executing properly (test classes are built i can see output from tests to console) but browser window never gets opened and test fails because of it. here is my ant file

Jenkins is 1.591 i installed it with default parameters as windows installation downloaded from their site.
Can it be something wrong with jenkins? Do i miss something?
As i mentioned earlier the problem was lack of UI permissions for Jenkins server.
1.configure Jenkins to run as service and make it login with real user name
2.Make sure that windows host that runs Jenkins logs on automaticaly after restart.

The manager documentation describes a special tag attribute that can be used to redeploy your application:
URL parameters include:
update: When set to true, any existing update will be undeployed first....
tag: Specifying a tag name, this allows associating the deployed webapp
with a tag or label. If the web application is undeployed, it can be
later redeployed when needed using only the tag.
Unfortunately, the ANT task documentation does not describe any support for this attribute...
Interestingly, the Maven plugin does support this, but switching build tool would be a rather extreme solution to this problem :-)
I am using Selenium testNG in eclipse to run my test cases.The testNg.xml file executes the test correctly.
But when I try to run in command prompt through ant the build is success but the test fails.
one peculiar thing happening is : when the driver i use to test is HtmlUnitdriver build is successful and also the test passes . But it fails when i use other browsers like firefox, chrome, explorer in my test case.
the build.xml i use is:

I appreciate any help.
I am trying to use the BuildInParallel option on MsBuild.
I have an NAnt & NAntContrib script e.g.
<project xmlns="http://nant.sf.net/release/0.90/nant.xsd" name="Css Manager Solution Build" ToolsVersion="3.5" default="deploy">
<target name="clean" description="Delete all previously compiled binaries.">
<delete>
<fileset>
<include name="**/bin/**" />
<include name="**/obj/**" />
<include name="**/*.suo" />
<include name="**/*.user" />
</fileset>
</delete>
</target>
<target name="deploy" description="Build and deploy all targets.">
<msbuild project="CssManager.sln" BuildInParallel="true">
<property name="Configuration" value="${configuration}"/>
<property name="OutDir" value="${bin.output.dir}"/>
</msbuild>
</target>
</project>
but I get this error message:
Unexpected attribute "BuildInParallel" on element <msbuild>
Please advise?
The MSBuild task of nant-contrib doesn't have a BuildInParallel attribute. You'll have to use the Maxcpucount command line argument.
<target name="deploy" description="Build and deploy all targets.">
<msbuild project="CssManager.sln" BuildInParallel="true">
<property name="Configuration" value="${configuration}"/>
<property name="OutDir" value="${bin.output.dir}"/>
<arg value="/maxcpucount:${environment::get-variable('NUMBER_OF_PROCESSORS')}"/>
</msbuild>
</target>
