Fail to run Gzoltar on Math-97 (Exception in thread "main" java.lang.NoSuchMethodError)

[fabiosalamone]

Context

I can't run Gzoltar vscode extension because I get the error: Exception in thread "main" java.lang.NoSuchMethodError: org.junit.runner.Description.getMethodName()Ljava/lang/String; I got the same error on Math-98, Math-95, Math-90 downloaded from Defects4j. The vscode extension works correctly with Math-100 and Math-101.

GZoltar arguments

I get the same error if I try to run the command from CLI. The command is: cd /home/except/Desktop/download_bugs/Math/97_IAE/.gzoltar/ && java -cp "build/":/home/except/.m2/repository/junit/junit/4.4/junit-4.4.jar:"hamcrest-core.jar":"gzoltarcli.jar" com.gzoltar.cli.Main listTestMethods /home/except/Desktop/download_bugs/Math/97_IAE/target/test-classes

Output

• List all (JUnit/TestNG) unit test cases in a provided classpath. Exception in thread "main" java.lang.NoSuchMethodError: org.junit.runner.Description.getMethodName()Ljava/lang/String; at com.gzoltar.internal.core.test.junit.FindJUnitTestMethods.find(FindJUnitTestMethods.java:76) at com.gzoltar.internal.core.test.FindTestMethods.findTestMethodsInClass(FindTestMethods.java:127) at com.gzoltar.internal.core.test.FindTestMethods.findTestMethodsInPath(FindTestMethods.java:102) at com.gzoltar.internal.core.test.FindTestMethods.findTestMethodsInPath(FindTestMethods.java:72) at com.gzoltar.cli.commands.ListTestMethods.execute(ListTestMethods.java:76) at com.gzoltar.cli.Main.execute(Main.java:105) at com.gzoltar.cli.Main.main(Main.java:40)

Environment

• OS: Ubuntu 21.04
• GZoltarcli.jar v1.7.3-SNAPSHOT.202104040547
• Visual Studio Code 1.64.2
• My $PATH is /home/except/.sdkman/candidates/java/current/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin:/home/except/defects4j/framework/bin

Additional Info

I found this https://github.com/GZoltar/gzoltar/issues/46 similar issue, but didn't helped me.

Hi @fabiosalamone,

Thanks for reporting this.

Could you please: (1) list all files under the .gzoltar directory, i.e., execute ls /home/except/Desktop/download_bugs/Math/97_IAE/.gzoltar/? (2) Set up your project to use a more recent version of JUnit, e.g., 4.11, and re-run the GZoltar VSCode extension?

-- Best, Jose

Hi @jose

thanks for your reply.

1. The output of the command is: drwxrwxr-x 5 except except 4096 mar 2 09:33 build
   -rw-r--r-- 1 except except 2206944 mar 2 09:33 gzoltaragent.jar
   -rw-r--r-- 1 except except 2146529 mar 2 09:33 gzoltarcli.jar
   -rw-r--r-- 1 except except 1499 mar 2 09:33 hamcrest-core.jar
   -rw-r--r-- 1 except except 381765 mar 2 09:33 junit.jar
   drwxrwxr-x 2 except except 4096 mar 2 09:33 sfl
   -rw-rw-r-- 1 except except 0 mar 2 09:33 tests.txt

If you need the recursive command, here is the output https://pastebin.com/UZTfcjw1

2. Anyway, changing JUnit from 4.4 to 4.11 in pom.xml of every project has worked! I tried with Math-97, Math-98, Math-95 and Math-90 and now the extension works generating the fault localization report.

Thanks, Fabio

Awesome, glad it worked. This is indeed similar to issue #46, i.e., an old/unsupported version of JUnit is on the classpath and GZoltar tries to use that one.

I've tried to address that by shading the Junit version required by GZoltar and including it in the gzoltar.jar file, but no success so far.
