Maven surefire and JDK 11

问题

I'm trying to get Maven surefire to run under JDK 11 but I keep getting these errors:

If I set reuseForks to true:

  Error occurred in starting fork, check output in log
  Process Exit Code: 1
  at org.apache.maven.plugin.surefire.booterclient.ForkStarter.fork(ForkStarter.java:670)
  at org.apache.maven.plugin.surefire.booterclient.ForkStarter.run(ForkStarter.java:283)
  at org.apache.maven.plugin.surefire.booterclient.ForkStarter.run(ForkStarter.java:246)

If I set it to false:

Execution default-test of goal org.apache.maven.plugins:maven-surefire-   plugin:3.0.0-M1:test
failed: java.lang.ClassNotFoundException: org.apache.maven.plugin.surefire.StartupReportConfiguration

I've found this and this link that describe the same problem but they don't have any solution.

For replication of this bug I created this git repo

Seems like while using a modular project to test, you need to have forkCount set as 0 :

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>3.0.0-M1</version>
    <configuration>
        <forkCount>0</forkCount> <!-- changed this to 0 -->
        <reuseForks>false</reuseForks>
        <!-- <threadCount>1</threadCount> --> <!-- shall be used with 'parallel' -->
        <printSummary>true</printSummary>
        <!-- <skipTests>false</skipTests> --> <!-- defaults to false -->

        <!-- run test in headless mode -->
        <systemPropertyVariables>
            <glass.platform>Monocle</glass.platform>
            <monocle.platform>Headless</monocle.platform>
            <prism.order>d3d</prism.order>
        </systemPropertyVariables>

        <argLine>
            --add-exports javafx.graphics/com.sun.javafx.application=ALL-UNNAMED
            --add-exports javafx.graphics/com.sun.glass.ui=ALL-UNNAMED
        </argLine>
    </configuration>
</plugin>

Quoting from this article

When module-info.java is present and fork process is enabled, surefire creates a mixed classpath with modules and unnamed modules causing module visibility issues and preventing the application to start.

Note: Disabling the forkCount and reuseForks configuration parameters, results in org.apache.maven.surefire.booter.SurefireBooterForkException being thrown, similar to the one reported in SUREFIRE-1528.

If this could help the developers at Maven community, the execution dump from the same run reads the following:

# Created at 2018-11-23T09:31:53.631
Corrupted STDOUT by directly writing to native stream in forked JVM 1. Stream 'Error occurred during initialization of boot layer'.
java.lang.IllegalArgumentException: Stream stdin corrupted. Expected comma after third character in command 'Error occurred during initialization of boot layer'.

    at java.base/java.lang.Thread.run(Thread.java:834)

Here is the line of code in the source repository.

I found the solution here:

https://winterbe.com/posts/2018/08/29/migrate-maven-projects-to-java-11-jigsaw/

I had to add.

<argLine>
    --illegal-access=permit
</argLine>

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.22.0</version>
    <configuration>
        <argLine>
            --illegal-access=permit
        </argLine>
    </configuration>
</plugin>
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-failsafe-plugin</artifactId>
    <version>2.22.0</version>
    <configuration>
        <argLine>
            --illegal-access=permit
        </argLine>
    </configuration>
</plugin>
