[ZhengJun003]

Environment:

• OS: Win10
• JDK: 11.0.5
• Java Extension:
  
  
  
  • Language Support for Java(TM) by Red Hat: 0.55.1
  
  
  • Debugger for Java: 0.24.0
  
  
  • Java Test Runner: 0.22.1
  
  

Repro steps:

1. git clone project: https://github.com/ZhengJun003/invisble-project.git
2. Run test project in the following level:
   
   
   
   • Workspace Root
   
   
   • Workspace Folder
   
   

Result:

Error: Failed to parse the JUnit launch arguments.

Cannot repro from my side. But leave it open to see if there is any customer encountering the same issue.

I got same problem when running the test. Output:
Error: Failed to parse the JUnit launch arguments

In our code base, this same issue was caused by having an abstract *Test.java class (a base class for multiple tests). The workaround was to annotate it with @Ignore, so VSC does not try to execute it.

I'm having the same issue. Just updated to JDK 11 and got this error.

It only happens when I try to run or debug an individual test/test class. I can run the whole test suite with no problem.

@EuniceB Is it possible to share a sample project about this issue?

[ssabogalp]

I have the same problem, My project is very simple maven project.

[jdneo]

@ssabogalp would you mind to share a sample project to us?

Look, this is the repoduction steps:
Create project from maven (that template is simply a hello world class with a test):

mvn archetype:generate -DgroupId=com.sample -DartifactId=java-project -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false
Then, open that folder in visual studio, when you open it, it asks:
"The workspace contains Java projects. Would you like to import them?
reply yes.
Then, above the test, will appear something like link that says "Run test | Debug test", you click "run test", and it says:
Error: Failed to parse the JUnit launch arguments
I created a lib folder and add this to class path (I think my problem might be here because in an IDE that is don in a GUI so i never did it manually before)

Restart visual studio. Still showing :

Error: Failed to parse the JUnit launch arguments

@ssabogalp

Java Test Runner currently only support JUnit 4 & 5. the archetype you generated is using JUnit 3, so the functionality won't work.

Please specify the version to 1.4: mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4

Also, the lib folder is only used to store the libs for the project that does not have build tools. Since you are using Maven now, so please add/remove the dependencies via editing the pom.xml.

Hi, my first try was added it to the pom, but it wasn't working so I tried the path. But now everything works, with the same dependency in pom:

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    <scope>test</scope>
</dependency>

I do not understand why it was failing. I believe the old dependency was in cache or something like that, but I restarted visual studio and it kept failing, but at some point it just worked in any way. Thanks.
