Maven Surefire: Error occured in starting fork

Question

When I am trying to run

mvn test

I always get the Error Message that maven-surefire error ocurred in starring fork. It has something to do with my local settings, on my colleagues PC it's working fine. I hope that somebody has an idea what is wrong with my pc :)

A part of the Error Message:

1. [ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.12.4:test (default-test) on project exercise00-assignment01: Error occurred in starting fork, check output in log -> [Help 1] org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.12.4:test (default-test) on project exercise00-assignment01: Error occurred in starting fork, check output in log

2. Caused by:

           at org.apache.maven.plugin.surefire.booterclient.ForkStarter.fork
       (ForkStarter.java:284)
   

I am using win10, jdk: 1.8.0_202, maven: 3.6.0

First please upgrade to at least 2.22.1 of maven-surefire-plugin.... – Almedaalmeeta

Where do I need to Update this Version? I can't modify the pom.xml – Arapaho

You can't modify the pom? does not make sense... – Almedaalmeeta

The pom.xml is from my course lecture, normally it should also work with this settings. On my colleagues PC it is working with this file. – Arapaho

Please show the full error output... – Almedaalmeeta

Answer 1

So I added the following Code to my pom.xml

<build>
        <pluginManagement>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-surefire-plugin</artifactId>
                    <version>3.0.0-M3</version>
                </plugin>
            </plugins>
        </pluginManagement>
    </build>

The Error Message changed:

[ERROR] Please refer to dump files (if any exist) [date].dump, [date]-jvmRun[N].dump and [date].dumpstream. [ERROR] Error occurred in starting fork, check output in log [ERROR] org.apache.maven.surefire.booter.SurefireBooterForkException: Error occurred in starting fork, check output in log [ERROR] at org.apache.maven.plugin.surefire.booterclient.ForkStarter.fork(ForkStarter.java:623) [ERROR] at org.apache.maven.plugin.surefire.booterclient.ForkStarter.run(ForkStarter.java:283) [ERROR] at org.apache.maven.plugin.surefire.booterclient.ForkStarter.run(ForkStarter.java:246)

Edit

I finally found my problem, in my path to the folder there was an '&' and windows couldn't handle it. This was the reason for the different Error Messages

Arapaho

Do you mean "&" is in the cmd.exe string? Mine is "cmd.exe /X /C "C:\Users\someone\tools\jdk-8u211\jre\bin\java -javaagent:C:\\Users\\someone\\.m2\\repository\\org\\jacoco\\org.jacoco.agent\\0.7.7.201606060606\\org.jacoco.agent-0.7.7.201606060606-runtime.jar=destfile=C:\\Users\\someone\\abc_repo\\bbb_repo\\services-parent\\payment-services-settlement-impl\\..\\target\\jacoco.exec,append=true -noverify -Duser.timezone=US/Central -Duser.language=en org.apache.maven.surefire.booter.ForkedBooter C:\Users\someone\AppData\Local\Temp\surefire5536645681570537156 ..." – Reaction

It is very long. Don't know how to make it short. – Reaction

Answer 2

I recently stuck in the same issue. After a lot of research, I got below the resolution

ForkCount should be set as "0"

Update your pom file as:-

<build>
<plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.19.1</version>
        <configuration>
        <forkCount>0</forkCount>
        <suiteXmlFiles>`enter code here`
        <suiteXmlFile>testng.xml</suiteXmlFile>
        </suiteXmlFiles>
        </configuration>
    </plugin>
</plugins>

I tried on 3.0.0-M3 version too and build is created successfully – Landseer

I think this appears to work because it is skipping tests. Be very careful about using it! Maven also warns about it now – Regazzi

Answer 3

Another solution that worked for me after trying numerous other suggestions was having a fork for every test class. Setting fork to 0 worked intermittently which I expected to work as when run with debug=true, they passed each time (no fork in debug). 3.0.0-M4

surefire forkcount documentation

<plugins>
    <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-surefire-plugin</artifactId>
       <configuration>
         <forkCount>number of test classes</forkCount>
       </configuration>
    </plugin>
</plugins>

Answer 4

I was getting this on my MacBook and it was fixed by restarting the computer. Not a very satisfying fix but it worked.
