How to use command-line using jdk7?

[Albert-Gong]

Hello,
I am trying to use PITest to mutate the code in Defects4J1.0, which requires jdk1.7.

Here is my java version

java version "1.7.0_80"
Java(TM) SE Runtime Environment (build 1.7.0_80-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)

I have tried several versions of PITest and finally found that PITest before 1.3 is compatible with jdk1.7.

Here is my script:

java 
  -cp    jars/pitest-1.3.0.jar:
         jars/pitest-command-line-1.3.0.jar: 
         jars/pitest-entry-1.3.0.jar: 
         jars/junit-4.12.jar: 
         jars/hamcrest-all-1.3.jar: 
         checkouts/lang-1f/target/classes/: 
         checkouts/lang-1f/target/test-classes \
         org.pitest.mutationtest.commandline.MutationCoverageReport \
         --reportDir ./report \
         --targetClasses org.apache.commons.lang3.math.NumberUtils \
         --targetTests org.apache.commons.lang3.BooleanUtilsTest \
         --sourceDirs ./checkouts/lang-1f/src/main/java \
         --verbose True

But then I got this exception

Exception in thread "main" java.lang.NoClassDefFoundError: com/thoughtworks/xstream/io/HierarchicalStreamWriter
	at org.pitest.mutationtest.tooling.EntryPoint.execute(EntryPoint.java:106)
	at org.pitest.mutationtest.tooling.EntryPoint.execute(EntryPoint.java:49)

	at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:358)

I ran the same script on another machine with jdk7 and got the same exception.

I wonder if it is possible to use the command line with jdk7, and if it is, which PITest version and jars should I use?

Thank you,
Albert

Not a maintainer but I have an old project with 1.3.2 CLI that runs on Java 8. So old is possibly.

You may want to verify that is just not a missing dependency since your not running in maven. It is listed as a dependency in the old POM.

pitest/pitest-entry/pom.xml

Line 140 in 2ca99e1

<groupId>com.thoughtworks.xstream</groupId>

Just noting the following:
https://github.com/hcoles/pitest/releases/tag/pitest-parent-1.3.0

#196 - Raise minimum java version to 7

Thanks for your reply,

I downloaded the pitest1.3.0 source code and ran

mvn install

Then I got

Still, I tried to use the pitest, pitest-entry and pitest-command-line jar and got the same exception as mentioned before, with both jdk7 and jdk8.

java version "1.7.0_80"

Maven's install doesn't combine the dependencies into the jar unless it uses the maven-shade-plugin telling it to do so and usually JARs created by it are very large.

Have you tried downloading the jar and including it in your classpath along with pitest?

Thank you, @rnveach,
After many efforts, now I can mutate all five projects in defects4j1.0, with some extra jars downloaded.

Below is the command to mutate Lang-1-f. I would like to share the script in case someone has the same problem.

jar_path='xxx/defects4j-1.0.0/jars'
build_path='xxx/defects4j-1.0.0/checkouts/lang-1f/target/classes'
build_test_path='xxx/defects4j-1.0.0/checkouts/lang-1f/target/test-classes'
targetClasse='org.apache.commons.lang3.math.NumberUtils'
targetTests='org.apache.commons.lang3.math.NumberUtilsTest'
sourceDirs='xxx/defects4j-1.0.0/checkouts/lang-1f/src'


java -cp \
$jar_path/xstream-1.4.8.jar:$jar_path/xmlpull_1_0_5.jar:$jar_path/pitest-1.3.0.jar:$jar_path/pitest-command-line-1.3.0.jar:$jar_path/pitest-entry-1.3.0.jar:$jar_path/junit-4.12.jar:$jar_path/hamcrest-all-1.3.jar:\

$build_test_path \
org.pitest.mutationtest.commandline.MutationCoverageReport \

Thank you again for your help.
