请帮我解决这个问题。我不太明白日志中的错误是什么意思。

在pom.xml中设置这一点对我来说很有效。 但是您应该查看文档以寻找其他解决方案 https://maven.apache.org/surefire/maven-surefire-plugin/examples/class-loading.html

       <plugin>

            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
                <!--these strange settings fixes a chrash and dumpstream from surefire when run from command line
                    Caused by: java.lang.ClassNotFoundException: org.apache.maven.surefire.booter.ForkedBooter
                -->
                <useSystemClassLoader>true</useSystemClassLoader>
                <useManifestOnlyJar>false</useManifestOnlyJar>
            </configuration>
        </plugin>

我在一个应用程序中遇到了同样的问题,即在运行测试时将大量XML记录到控制台。我认为这个问题与测试fork将其控制台日志发送到主maven线程以输出到屏幕的方式有关。

在我的测试日志文件中,我通过将有问题的类的日志设置为WARN来解决这个问题。

如logback-test.xml

<configuration debug="true">
  <include resource="org/springframework/boot/logging/logback/defaults.xml" />
  <include resource="org/springframework/boot/logging/logback/console-appender.xml" />

  <logger name="com.foo.ClassWithLotsOfXmlLogging" level="WARN" />

  <root level="INFO">
    <appender-ref ref="CONSOLE"/>
  </root>
</configuration>

我最近在JHipster 6.10.5使用spring-boot 2.2.7生成的应用程序中遇到了同样的问题。RELEASE和maven surefire插件3.0.0-M4。这是由于非常长的测试日志造成的超时。通过在pom.xml中的maven-surefire-plugin(在pluginManagement下)中添加以下配置参数来解决:

1200年< forkedProcessExitTimeoutInSeconds > < / forkedProcessExitTimeoutInSeconds >

看到https://maven.apache.org/surefire/maven-surefire-plugin/test-mojo.html forkedProcessExitTimeoutInSeconds

我的决心是将Jenkinsfile中提到的超时时间从90更改为120。

pipeline {
    agent { label projectName }

options {
    disableConcurrentBuilds()
    buildDiscarder(logRotator(numToKeepStr:'5'))
    timeout(time: 90, unit: 'MINUTES')
}

使用maven surefire 2.21.0我解决了reuseForks选项值从true变为false的问题:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.21.0</version>
            <configuration>
                <reuseForks>false</reuseForks>
            </configuration>
        </plugin>
    </plugins>
</build>

我正在构建的整个配置部分是这样的:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.21.0</version>
            <configuration>
                <testFailureIgnore>true</testFailureIgnore>
                <skip>false</skip>
                <reuseForks>false</reuseForks>
                <argLine>-Xmx1024m -XX:MaxPermSize=256m</argLine>
                <argLine>-Dfile.encoding=UTF-8</argLine>
                <useSystemClassLoader>false</useSystemClassLoader>
                <includes>
                    <!--Test* classes for the app testing -->
                    <include>**/directory/Test*.java</include>
                </includes>
            </configuration>
        </plugin>
    </plugins>
</build>

您可以使用以下命令。因为你的单元测试需要分叉。关于你在单元测试中使用线程的问题。

mvn test -DforkCount=2

我希望。它有帮助。
