Maven surefire和JDK 11

Question

我试图让Maven确定在JDK 11下运行,但我不断收到这些错误:

1. 如果我设置reuseForks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)

2. 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

我发现这个和这个链接描述了同样的问题,但他们没有任何解决方案.

为了复制这个bug,我创建了这个git repo

似乎在使用模块化项目时test,您需要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>

引用本文

如果module-info.java存在且fork进程已启用,则surefire会创建一个包含模块和未命名模块的混合类路径,从而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org.apache.maven.surefire.booter.SurefireBooterForkException抛出,类似于 SUREFIRE-1528中报告的那样.

如果这可以帮助Maven社区的开发人员,则来自同一运行的执行转储将显示以下内容:

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

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

这是源存储库中的代码行.

我不得不补充。
