最近来到一个新项目,我试图编译我们的源代码。昨天一切都很好,但今天就不一样了。

每次我在一个模块上运行mvn clean install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 :

Tests run: 0, Failures: 0, Errors: 0, Skipped: 0

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 without properly saying goodbye. VM crash or System.exit called?

我在Debian 9 (Stretch) 64位上运行,使用OpenJDK 1.8.0_181, Maven 3.5.4,在我的公司代理后面工作,我在~/.m2/settings.xml中配置了代理。

奇怪的是,如果我没记错的话,最新的Surefire版本是2.22.1。我试图指定插件版本,但它没有得到更新,否则任何POM(父、祖父或这个)中都没有插件版本规范。

我成功地迫使Maven将Surefire版本更改为最新版本,但现在情况更糟了:

我发现了这个解决方法并修正了我的测试:配置maven-surefire-plugin不使用系统类加载器。

其他回答

我最近在詹金斯上设置了专家工作,陷入了同样的问题。我采纳了修改JAVA env变量的建议,并确认问题已经解决。这就是我的测试方法。

成为“jenkins”用户,并将文件夹更改为为作业设置的工作区项目名称。

 $ _JAVA_OPTIONS=-Djdk.net.URLClassPath.disableClassPathURLCheck=true mvn clean install -U

 $ lsb_release -rd
 Description:   Ubuntu 16.04.5 LTS
 Release:   16.04

 $ mvn -v
 Apache Maven 3.3.9
 Maven home: /usr/share/maven
 Java version: 1.8.0_181, vendor: Oracle Corporation
 Java home: /usr/lib/jvm/java-8-openjdk-amd64/jre
 Default locale: en_US, platform encoding: UTF-8
 OS name: "linux", version: "4.4.0-131-generic", arch: "amd64", family: "unix"

把这个添加到maven-surefire-plugin中,我解决了这个问题:

    <plugin>    
        <groupId>org.apache.maven.plugins</groupId> 
        <artifactId>maven-surefire-plugin</artifactId>  
        <configuration>
            <forkCount>0</forkCount>
        </configuration>
    </plugin>

对于那些寻找Docker Maven相关答案的人:3.5。在GitLab CI上的x-jdk-8,参见这个GitHub问题。

似乎是3.5.4-jdk-8镜像导致升级到一个小Java版本,这在某种程度上影响了Surefire的分叉机制。

回滚到3.5.3-jdk-8映像为我修复了这个问题,我的GitLab CI服务器使用Surefire 2.20.1构建Java 1.8代码。

基本上是JDK版本和maven-surefire插件版本之间的不兼容,在我的情况下,JDK 11.0.5不能与surefire 3.0.0-M4兼容,我必须切换到3.0.0-M3,它可以工作。将forkCount设置为0并不能解决这个问题,因为它破坏了Jacoco报告。
