Exception in thread "main" java.lang.NoClassDefFoundError: and Caused by: java.lang.ClassNotFoundException: and at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) Could not find the main class: and. Program will exit.

Package com.android.cts.TestHost is exists in Jar file.which

I had the same issue by using cygwin

I found the solution on this blog

You just have to do the modification of those two line in the script startcts :

JARS=`cygpath -w -p ${CTS_LIB}:${DDM_LIB}:${JUNIT_LIB}:${HOSTTEST_LIB}`
java ${JAVA_OPTS} -cp ${JARS} com.android.cts.TestHost `cygpath -w ${CONFIG}` "$@" ${DDCONFIG}

Then I was able to have the CTS prompt
