Question

由于我不知道某个事件，因此在我的Ubuntu 18.04中无法再调用if coordinate not in specialCoordinates。（自4月开始运行）。 mvn test或我尝试过的任何其他生命周期阶段都很好。

如果例如我在克隆到mvn install -DskipTests=true的Apache Commons IO的最新版本中运行mvn test，则显示

/home/reichelt/commons-io/

目标/保证报告包含很多重复

我尝试过的任何其他项目都显示出类似的行为。

我尝试下载maven 3.5.4，将其解压缩，通过# Created on 2018-10-31T18:31:48.243 Error: Could not find or load main class org.apache.maven.surefire.booter.ForkedBooter将其添加到路径中并运行较新的版本，但这并没有改变任何内容（而export PATH=/home/reichelt/Downloads/apache-maven-3.5.4-bin/apache-maven-3.5.4/bin:$PATH可以正常工作并显示较新的版本版）。 Maven 3.5.0也是如此。

Maven error: Could not find or load main class org.codehaus.plexus.classworlds.launcher.Launcher建议设置mvn -version和export M3_HOME=/usr/share/maven会有所帮助，但不幸的是，它没有帮助。

我尝试删除export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/，但不幸的是，这也无济于事。

使用~/.m2在docker容器中运行并运行

docker run -it ubuntu

产生相同的行为，所以这似乎不仅仅是我的安装问题。

运行apt update apt install -y openjdk-8-jdk maven git mvn -version git clone https://github.com/apache/commons-io.git cd commons-io/ mvn test和

docker run -it fedora bash

运行测试出乎意料。

有人知道如何解决此问题/解决该问题吗？

编辑就像该消息所暗示的那样，yum install java-1.8.0-openjdk.x86_64* yum install wget wget http://ftp-stud.hs-esslingen.de/pub/Mirrors/ftp.apache.org/dist/maven/maven-3/3.5.4/binaries/apache-maven-3.5.4-bin.tar.gz tar -xvf apache-maven-3.5.4-bin.tar.gz yum install git export PATH=/apache-maven-3.5.4/bin:$PATH mvn -version git clone https://github.com/apache/commons-io.git cd commons-io/ mvn test似乎是一个问题，无法找到。 https://maven.apache.org/surefire/maven-surefire-plugin/examples/class-loading.html描述了surefire可以由引导程序jar中的隔离类加载器或仅清单的jar使用。似乎默认情况下，我使用的是清单清单的jar，其中包含以下内容：

ForkedBooter

这对我来说似乎不错：Manifest-Version: 1.0 Class-Path: file:/home/reichelt/.m2/repository/org/apache/maven/surefi re/surefire-booter/2.21.0/surefire-booter-2.21.0.jar file:/home/reich elt/.m2/repository/org/apache/maven/surefire/surefire-api/2.21.0/sure fire-api-2.21.0.jar file:/home/reichelt/.m2/repository/org/apache/mav en/surefire/surefire-logger-api/2.21.0/surefire-logger-api-2.21.0.jar file:/home/reichelt/commons-io/target/test-classes/ file:/home/reich elt/commons-io/target/classes/ file:/home/reichelt/.m2/repository/jun it/junit/4.12/junit-4.12.jar file:/home/reichelt/.m2/repository/org/h amcrest/hamcrest-core/1.3/hamcrest-core-1.3.jar file:/home/reichelt/. m2/repository/org/apache/maven/surefire/surefire-junit4/2.21.0/surefi re-junit4-2.21.0.jar Main-Class: org.apache.maven.surefire.booter.ForkedBooter很好，并且包含/home/reichelt/.m2/repository/org/apache/maven/surefire/surefire-booter/2.21.0/surefire-booter-2.21.0.jar的类文件。

通过添加

org.apache.maven.surefire.booter.ForkedBooter

到pom，再次运行构建。这似乎是不使用<useSystemClassLoader>true</useSystemClassLoader> <useManifestOnlyJar>false</useManifestOnlyJar>的解决方案。尽管这是一种解决方法，但我仍然想了解：我可以进一步调试此问题，以找到在当前的Ubuntu上不起作用的原因吗？由于它不能与其他Maven版本一起使用（即使在新的Ubuntu Docker容器中也可以），但在Fedora容器上也可以使用，因此我认为原因某种程度上与Ubuntu默认配置有关。

Answer 1

有趣的故事：确实，这是一个OpenJDK更新问题。

我通过sudo zcat /var/log/apt/history.log.1.gz | less阅读了我的上一个历史记录（取决于logrotating，它是0.1，可以是其他任何东西）。这表明今天早上运行了更新：

Start-Date: 2018-10-31  10:38:04
Commandline: /usr/bin/unattended-upgrade
Upgrade: openjdk-8-jdk:amd64 (8u181-b13-0ubuntu0.18.04.1, 8u181-b13-1ubuntu0.18.04.1), openjdk-8-jre:amd64 (8u181-b13-0ubuntu0.18.04.1, 8u181-b13-1ubuntu0.18.04.1), openjdk-8-jdk-headless:amd64 (8u181-b13-0ubuntu0.18.04.1, 8u181-b13-1ubuntu0.18.04.1), openjdk-8-jre-headless:amd64 (8u181-b13-0ubuntu0.18.04.1, 8u181-b13-1ubuntu0.18.04.1)
End-Date: 2018-10-31  10:38:09

因此由于某种原因，OpenJDK 8u181似乎与maven 3.5.2和surefire不兼容。由于已经安装了软件包升级，因此我再次使用sudo apt install openjdk-8-jdk=8u162-b12-1 openjdk-8-jre=8u162-b12-1 openjdk-8-jdk-headless=8u162-b12-1 openjdk-8-jre-headless=8u162-b12-1进行了降级。现在测试再次起作用。

在https://www.oracle.com/technetwork/java/javase/8u-relnotes-2225394.html中，Java 8u171、8u172和8u181似乎没有包含更新，这些更新使得使用sureman-only罐的surefire不可能实现，但我只是在上面略过一眼，并没有深入探究该错误。报告。

编辑，该错误已在OpenJDK上报告：https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=911925

编辑2 ，该错误已在Java 1.8.0_191中修复，并且mvn测试再次正常运行。

Answer 2

今天遇到了同样的问题。不确定最好的长期修复方法，但是将maven-surefire-plugin的forkCount设置为0似乎已经为我修复了。不幸的是，这可能会使测试花费更长的时间。

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <configuration>
    <forkCount>0</forkCount>
    <reuseForks>true</reuseForks>
    <argLine>-Xmx1024m -XX:MaxPermSize=256m</argLine>
  </configuration>
</plugin>

希望有帮助。
