Maven surefire和JDK 11 [英] Maven surefire and JDK 11

问题描述

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

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

1. 如果我将reuseForks设置为true:

1. 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)

1. 如果我将其设置为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

我找到了这和

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

为复制此错误，我创建了此git存储库

推荐答案

似乎在将模块化项目用于test时，您需要将forkCount设置为0:

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>

在本文中引用

存在module-info.java且启用了 的fork过程时，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.

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.

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

---

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.

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:

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