将我们的微服务pom升级为使用Spring Boot 2.1.0 RELEASE（从2.0.5 RELEASE开始）后，我们开始偶尔遇到构建失败的情况。有人看到了这个并且有解决方案（请参见下面的错误）吗？
Maven命令：mvn全新安装
在测试执行过程中生成的带有以下注释的测试失败：
@RunWith(SpringRunner.class)
@SpringBootTest
Java ：
java version "10.0.2" 2018-07-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.2+13)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.2+13, mixed mode)
我们pom中的片段似乎是导致此问题的原因。
来自pom的Surefire插件：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<!-- Below 955m we get failures "VM crash or System.exit called?". Set with safety margin. -->

<excludes>
<exclude>**/*IT.java</exclude>
<exclude>**/*ManualTest.java</exclude>
</excludes>
<skipTests>false</skipTests>
</configuration>
</plugin>
我们还使用Jacoco ：
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.8.2</version>
<configuration>
<excludes>
<exclude>**/is/applicon/wsapi/*/*.*</exclude>

实际上，错误情况看起来像是有关无法在jwm中派生进程的。
启动分叉时发生错误，请在日志[ERROR]中检查输出 退出代码：134
以thek标记删除jacoco-maven-plugin的另一种方法，如果分叉计数与您的情况无关，则可以覆盖forkCount的{{1}}。
maven-surefire-plugin您还可以查看有关forking parallel test processes的详细信息。
