IntelliJ Error when running unit test: Could not find or load main class ${surefireArgLine}

Question

I get the following error when running Unit tests in IntelliJ: Error: Could not find or load main class ${surefireArgLine}. I am using maven and in pom.xml I have:

<properties>
    ...
    <surefire.argLine />
</properties>

   ...

I had the same problem and i think i found the solution on the vertx-issue tracker.

In short you have to configure your IntelliJ Maven (surefire plugin) integration to behave differently.

This works for me in IntelliJ 14.1.6 with mvn 3.3.9 Preferences -> Build,Execution,Deployment -> Build Tools -> Maven -> Running Tests

For IntelliJ 2019 and above Settings-> Build,Execution,Deployment -> Build Tools -> Maven -> Running Tests

Uncheck argLine

Same problem, but sans surefire. Getting error "Could not find or load main class ${argLine}". This works. – paultamalunas Jul 30 '17 at 22:59

Thank you...what are the chances of finding such a post when trying to make changes to a build and making sure it does not have side effects for the developers...god bless stackoverflow. – Beezer Sep 04 '17 at 12:50

Similar problem for me with error message containing @{argLine}. Resolution works. – Robert DROP TABLE STUDENTS Sep 17 '18 at 12:12
problem still happening, unchecking `argLine` fixed for me – Doug Jul 09 '19 at 09:42

I was able to fix this error in Netbeans by changing the surefire-plugin version to 2.10 and removing

<argLine>-Xmx1024m -XX:MaxPermSize=256m ${argLine}</argLine>

from the maven-surefire-plugin configuration. Instead i have created a property argLine that is picked automatically by surefire.

<properties>
    <argLine>-Xmx1024m -XX:MaxPermSize=256m</argLine>
  </properties>

<build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.10</version>
      </plugin>

Now, i can run and debug single files and test methods. And Code Coverage is working as expected.

This works for IntelliJ too. This option is [mentioned in the JaCoCo documentation](https://www.jacoco.org/jacoco/trunk/doc/prepare-agent-mojo.html). — vossad01, Jul 03 '18 at 18:57

Update of pom.xml solved my problem.

<argLine>${surefire.argLine}</argLine>

Complete plugin info in pom.xml

    <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>

                <workingDirectory>${project.build.directory}</workingDirectory>   
                <jvm>${env.JDK1_8_HOME}\bin\java</jvm>   
                <argLine>${surefire.argLine}</argLine>
            </configuration>
            <dependencies>
                <dependency>

Was looking for this and found this project "fix" it in this thread

Basically define your jacocoArgLine var name as empty project property. Then in surefire configuration use @{jacocoArgLine} instead of dollar prefix.

I found out that I have to run my test case from maven with mvn -Dtest=TestCircle test not directly from IDE.

Did you ever found another sollution for this? I need to run it from my IDE to be able to use debug mode. – LisaMM Oct 01 '15 at 12:58
Unfortunatelly I haven't found another solution for this. – BlueLettuce16 Oct 02 '15 at 07:40

@LisaMM you can debug tests without running the tests in an IDE. Just start the tests with *mvnDebug* on the command line. Then use your favorite IDE to connect to the command line process. Google for "remote debug" in your favorite IDE. – Hendrik Jander Feb 13 '16 at 09:18
@BlueLettuce16 solution proposed by "jah" (has 200+ ups) is much better, could you please mark accordingly? – sergpank Jan 21 '20 at 14:20

For a more permanent fix for every new project add the following to your IntelliJ IDEA Custom VM Options:

Help > Edit Custom VM options
Add: -Didea.maven.surefire.disable.argLine=true

This will deactivate surefire for all new projects you open.
