I want integrate CPD (Copy-Paste-Detection) to my iOS project. I read about it here and here.

To automatically determine CopyPaste in the code I’m using bash script:

echo "Checking files in ${SOURCE_ROOT}"
JARS_DIR=${PROJECT_DIR}/CPD
FULL_PATH_TO_CPD_XML_OUTPUT=${PROJECT_DIR}/cpd-output.xml

# Running CPD
java -classpath "${JARS_DIR}/ObjCLanguage-0.0.5-SNAPSHOT.jar:${JARS_DIR}/pmd.jar" net.sourceforge.pmd.cpd.CPD --minimum-tokens 100 --files "${SOURCE_ROOT}" -v --language ObjectiveC --encoding UTF-8 --format net.sourceforge.pmd.cpd.XMLRenderer > "${FULL_PATH_TO_CPD_XML_OUTPUT}"

# Running self :)
${BUILT_PRODUCTS_DIR} -cpd-xml "${FULL_PATH_TO_CPD_XML_OUTPUT}"

That code create cpd-output.xml file. But take me an error at compile time “Command /bin/sh failed with exit code 126”. Here is log copy http://pastebin.com/359k1Wni
I took the code from this example project
Error is going then I comment this string: 

${BUILT_PRODUCTS_DIR} -cpd-xml "${FULL_PATH_TO_CPD_XML_OUTPUT}"

I tried to find what ever information about this error, but found only a few of these problems without answers. I’m not know anything about bash scripting. I will be happy with any advice.
Thank you for your attention.

P.S. Author of following the script written:

In order to integrate XCode and the CPD, we will add to the Build
Phases target with the project, Run Script phase, conventionally
consisting of several parts: Actually calling cpd Parsing
cpd-output.xml Output in the “right format”

    The problem was in the wrong script. I give a revised script, which logs have been added:

    echo "Checking files in ${SOURCE_ROOT}"
CPD_DIR=${PROJECT_DIR}/CPD
JARS_DIR=${PROJECT_DIR}/CPD
FULL_PATH_TO_CPD_XML_OUTPUT=${PROJECT_DIR}/cpd-output.xml
OBJC_JAR_LIBRARY=${JARS_DIR}/ObjCLanguage-0.0.5-SNAPSHOT.jar

echo [DEBUG] CPD_DIR = ${CPD_DIR}
echo [DEBUG] JARS_DIR = ${JARS_DIR}
echo [DEBUG] FULL_PATH_TO_CPD_XML_OUTPUT = ${FULL_PATH_TO_CPD_XML_OUTPUT}
echo [DEBUG] OBJC_JAR_LIBRARY = ${OBJC_JAR_LIBRARY}
echo [DEBUG] SOURCE_ROOT = ${SOURCE_ROOT}

# Running CPD
java -classpath "${OBJC_JAR_LIBRARY}:${JARS_DIR}/pmd.jar" net.sourceforge.pmd.cpd.CPD --minimum-tokens 200 --files "${SOURCE_ROOT}" -v --language ObjectiveC --encoding UTF-8 --format net.sourceforge.pmd.cpd.XMLRenderer > "${FULL_PATH_TO_CPD_XML_OUTPUT}"

CPD_EXECUTABLE="${CPD_DIR}/CPDObjective-C"
if [ ! -f "${CPD_EXECUTABLE}" ];
then
echo "CPD executable file is not found: " ${CPD_EXECUTABLE}
fi
echo "Running ${CPD_EXECUTABLE} -cpd-xml ${FULL_PATH_TO_CPD_XML_OUTPUT}"
"${CPD_EXECUTABLE}" -cpd-xml "${FULL_PATH_TO_CPD_XML_OUTPUT}"

    Here is source code of sample Copy-Paste-Detect
