For our trace, we will be examining the second screenshot, analyzing the case of a COMPILE ERROR
Following our code:
-rm -rf student-submission <— Attempts to remove any current student-submission. Return code: 0 echo “Cloning into student submission” <— Output: “Cloning into student submission” Error: “” Return code:0
git clone $1 student-submission 2> /dev/null <— Return code: 0 echo “Cloning completed!” <— Output: “Cloning completed” Return code: 0 error=0
javac -target 1.8 -cp “.;..lib/hamcrest-core-1.3.jar:lib/junit-4.13.2.jar” ListExamples.java TestListExamples.java <— Return code:0 rm ListExamples.class
CP=”..;../lib/hamcrest-core-1.3.jar:../lib/junit-4.13.2.jar”
cd student-submission

ls -a > fileList.txt
if [ $(grep -c “ListExamples.java” fileList.txt) -eq 0 ] <— Condition is false since file “ListExamples.java” was found| Return code:0 then
echo “"ListExamples.java" not found, check to see that you’ve submitted the proper files” <— Not run since if is false
exit 1 <— Not run since if is false
fi

echo “ATTEMPTING TO COMPILE…” <— Output: “ATTEMPTING TO COMPILE…” Return code: 0
javac -cp $CP *.java <— Compiles files ending with .java, fails to compile and prints error Return code: 1
if [ $? -ne 0 ] <– Return code is currently 1 so does not equal 0 therefore this evaluates to true since 1 != 0
then <– Runs since if was true
echo “COMPILE ERROR, Score: 0.00/2.00” <— Output: “COMPILE ERROR, Score: 0.00/2.00”
echo “Make sure that your program compiles properly” <— Output: “Make sure that your program compiles properly”
exit 1 <– Script exits with exit code 1
fi
Since our script exited with this if statement, the code that comes after will not run.
