Question

我正在尝试使Maven surefire在JDK 11下运行，但我不断收到这些错误：

如果我将reuseForks设置为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)

如果将其设置为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

我发现this和this链接描述了相同的问题，但是它们没有任何解决方案。

为了复制此错误，我创建了this git repo

Answer 1

似乎在将模块化项目用于test时，您需要将forkCount设置为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>

引用from this article

当module-info.java存在且分叉进程已启用时，surefire 使用模块和未命名模块创建 mixed 类路径，导致模块可见性问题，并阻止应用程序启动。

注意：禁用forkCount和reuseForks配置参数会导致抛出org.apache.maven.surefire.booter.SurefireBooterForkException，类似于报告的那个在SUREFIRE-1528中。

如果这可以帮助Maven社区的开发人员，则同一运行中的执行转储将读取以下内容：

# Created at 2018-11-23T09:31:53.631

Here is the line of code in the source repository.

我在这里找到了解决方法：

我必须添加。

<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>

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

Maven surefire和JDK 11
