最近来到一个新项目,我正在尝试编译我们的源代码.昨天一切都很好,但今天是另一个故事.
每次我在mvn clean install模块上运行时,一旦到达测试,它就会崩溃成一个错误:
[INFO] --- maven-surefire-plugin:2.18.1:test (default-test) @ recorder ---

Error: Could not find or load main class org.apache.maven.surefire.booter.ForkedBooter
Results :

后来:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.18.1:test (default-test) on project recorder: Execution default-test of goal org.apache.maven.plugins:maven-surefire-plugin:2.18.1:test failed: The forked VM terminated …在Java中,System.exit(0)以下代码有或没有区别？
public class TestExit
{
public static void main(String[] args)
{
System.out.println("hello world");
System.exit(0); // is it necessary? And when it must be called?
}
}
该文件说:"这种方法永远不会正常返回." 这是什么意思？
特别是,我想做这样的事情:
mvn -DjvmArgs="-Xmx2000m -Xms1000m -XX:PermSize=512m -XX:MaxPermSize=512m" jetty:run -Pmyprofile
哦,我想这样做而不必修改pom文件或设置任何环境变量等
运行maven(3.5.2)构建Spring Boot 2.0.2.RELEASE应用程序(由Web初始化程序生成,具有Web依赖性)无法执行maven-surefire-plugin说:
错误:无法找到或加载主类org.apache.maven.surefire.booter.ForkedBooter
引起:java.lang.ClassNotFoundException:org.apache.maven.surefire.booter.ForkedBooter
为什么会这样？这是boot + surefire集成中的一个问题=一个bug？
作为参考,似乎相关的依赖关系是:

我正在开发一个相当复杂的java项目,它有许多依赖项和许多单元测试.
我在mac(mavericks)上使用java 1.6.0_65,使用maven 3.0.5和maven-surefire-plugin:2.16在几个forks中运行.我的问题是使用多个forks运行此设置会导致fork退出:
"分叉的虚拟机终止了,没有说再见.虚拟机崩溃或System.exit调用？"
只使用一个fork运行它不会产生问题(并且一切都通过)
有一些关于这个问题的信息包括这个StackOverflow问题和这个万无一失的bug(现在似乎已经解决了)
我知道这种情况的"答案"是在我的代码中找到什么叫System.exit() - 我找不到任何东西.
或者是什么原因导致我的JVM崩溃 - 没有hs_pid崩溃报告.
我的问题是我可以用什么样的策略来找到找到这个原因的？ 为了澄清,我对上面提到的答案不感兴趣,但是找到它的起源.(或者甚至更好地回答可能造成这种情况的不同答案)
我的Surefire配置是:(但我确实尝试过其他组合)
<parallel>classes</parallel>
<threadCount>1</threadCount>
<forkCount>1C</forkCount>
<reuseForks>false</reuseForks>
<useSystemClassLoader>false</useSystemClassLoader>
<useManifestOnlyJar>true</useManifestOnlyJar>

org.apache.maven.lifecycle.LifecycleExecutionException: Failed to …我在Eclipse中有几个JUnit运行配置,我需要在命令行上复制才能使用第三方分析工具.到目前为止,我刚刚通过查看运行配置并编写相应的类路径和命令行参数来手动编写命令行.
Eclipse的运行配置(普通,JUnit或其他)最终必须归结为命令行,那么我如何以及在何处找到它？
按照标题:我正试图从容器化的詹金斯奴隶那里运行Maven自动化测试,并且经过一个星期的斗争,现在我已经没有想法了.它在具有4G RAM的AWS实例上工作,但在不受限制的(在RAM和CPU上)容器中,它失败并出现如下错误.它运行的唯一情况是我禁用Failsafe插件的分支,但这不是一个选项.
我尝试了各种各样的Java/Maven/Failsafe/Surefire选项,我可以用谷歌找到但没有运气(比如添加全局Java -Xmx选项以及pom.xml中的每个插件).
有没有人像这样成功地运行它？
这似乎应该更容易处理,但我现在已经拉了我头上的所有头发我应该有.我仍然不喜欢承认失败的想法.请帮忙!
这些是插件在失败后创建的转储:

[INFO] jacoco.agent.argLine set to -javaagent:<...>/.m2/repository/org/jacoco/org.jacoco.agent/0.7.2.201409121644/org.jacoco.agent-0.7.2.201409121644-runtime.jar=destfile=<...>/target/jacoco.exec
但是,maven尝试运行JaCoCo时尚未创建.exec:
[INFO] Skipping JaCoCo execution due to missing execution data file:<...>/target/jacoco.exec
在maven跳过JaCoCo执行后,jacoco.exec最终会被创建.因此,如果我在没有清理的情况下重新运行构建,我仍然可以生成AHP报告.
我已经在其他各种问题中看到,我需要小心使用Maven Surefire和JaCoCo.但是,我没有在我的Surefire插件或任何插件中明确使用argLine.我开始怀疑其他插件之一是否像JaCoCo一样自动劫持argLine参数.
以下是使用的所有插件的列表:
我确实在构建输出中看到一条可疑消息:
[INFO] --- maven-compiler-plugin:3.0:compile (default-compile) @ <module> ---
[INFO] Changes detected - recompiling the module!
我不确定这是否相关,但它在跳过消息之前出现了两次,并且没有出现在JaCoCo正常工作的模块中.
有任何想法吗？
