Question

我遇到Maven的问题，不尊重用户的settings.xml文件中的<localRepository>值。

我的环境是使用Chef配置的Vagrant实例。我使用Chef Maven cookbook安装了Maven。

Maven运行正常，除了它忽略了我在ssh用户的settings.xml中定义的本地存储库：

vagrant@vagrant-ubuntu-trusty-64:/vagrant$ cat ~/.m2/settings.xml 
<?xml version="1.0" encoding="UTF-8"?>

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

  <localRepository>/vagrant/.m2/repository</localRepository>

</settings>

如您所见，我正在尝试通过将Maven Local Repository放置在Host OS和Guest OS共享的文件夹下的子目录中来共享Host OS和Guest OS之间的本地存储库：{{ 1}}

但是，当我使用Debug选项集运行Maven时：/vagrant/.m2/repository Maven通知我它正在正确读取settings.xml文件，但由于某种原因没有正确设置本地存储库：

mvn -X

Maven错误地将本地存储库设置为默认vagrant@vagrant-ubuntu-trusty-64:/vagrant$ mvn -X Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-10T16:41:47+00:00) Maven home: /usr/local/maven Java version: 1.8.0_65, vendor: Oracle Corporation Java home: /usr/lib/jvm/jdk1.8.0_65/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "3.13.0-85-generic", arch: "amd64", family: "unix" [DEBUG] Created new class realm maven.api [DEBUG] Importing foreign packages into class realm maven.api [DEBUG] Imported: javax.enterprise.inject.* < plexus.core [DEBUG] Imported: javax.enterprise.util.* < plexus.core [DEBUG] Imported: javax.inject.* < plexus.core [DEBUG] Imported: org.apache.maven.* < plexus.core [DEBUG] Imported: org.apache.maven.artifact < plexus.core [DEBUG] Imported: org.apache.maven.classrealm < plexus.core [DEBUG] Imported: org.apache.maven.cli < plexus.core [DEBUG] Imported: org.apache.maven.configuration < plexus.core [DEBUG] Imported: org.apache.maven.exception < plexus.core [DEBUG] Imported: org.apache.maven.execution < plexus.core [DEBUG] Imported: org.apache.maven.execution.scope < plexus.core [DEBUG] Imported: org.apache.maven.lifecycle < plexus.core [DEBUG] Imported: org.apache.maven.model < plexus.core [DEBUG] Imported: org.apache.maven.monitor < plexus.core [DEBUG] Imported: org.apache.maven.plugin < plexus.core [DEBUG] Imported: org.apache.maven.profiles < plexus.core [DEBUG] Imported: org.apache.maven.project < plexus.core [DEBUG] Imported: org.apache.maven.reporting < plexus.core [DEBUG] Imported: org.apache.maven.repository < plexus.core [DEBUG] Imported: org.apache.maven.rtinfo < plexus.core [DEBUG] Imported: org.apache.maven.settings < plexus.core [DEBUG] Imported: org.apache.maven.toolchain < plexus.core [DEBUG] Imported: org.apache.maven.usability < plexus.core [DEBUG] Imported: org.apache.maven.wagon.* < plexus.core [DEBUG] Imported: org.apache.maven.wagon.authentication < plexus.core [DEBUG] Imported: org.apache.maven.wagon.authorization < plexus.core [DEBUG] Imported: org.apache.maven.wagon.events < plexus.core [DEBUG] Imported: org.apache.maven.wagon.observers < plexus.core [DEBUG] Imported: org.apache.maven.wagon.proxy < plexus.core [DEBUG] Imported: org.apache.maven.wagon.repository < plexus.core [DEBUG] Imported: org.apache.maven.wagon.resource < plexus.core [DEBUG] Imported: org.codehaus.classworlds < plexus.core [DEBUG] Imported: org.codehaus.plexus.* < plexus.core [DEBUG] Imported: org.codehaus.plexus.classworlds < plexus.core [DEBUG] Imported: org.codehaus.plexus.component < plexus.core [DEBUG] Imported: org.codehaus.plexus.configuration < plexus.core [DEBUG] Imported: org.codehaus.plexus.container < plexus.core [DEBUG] Imported: org.codehaus.plexus.context < plexus.core [DEBUG] Imported: org.codehaus.plexus.lifecycle < plexus.core [DEBUG] Imported: org.codehaus.plexus.logging < plexus.core [DEBUG] Imported: org.codehaus.plexus.personality < plexus.core [DEBUG] Imported: org.codehaus.plexus.util.xml.Xpp3Dom < plexus.core [DEBUG] Imported: org.codehaus.plexus.util.xml.pull.XmlPullParser < plexus.core [DEBUG] Imported: org.codehaus.plexus.util.xml.pull.XmlPullParserException < plexus.core [DEBUG] Imported: org.codehaus.plexus.util.xml.pull.XmlSerializer < plexus.core [DEBUG] Imported: org.eclipse.aether.* < plexus.core [DEBUG] Imported: org.eclipse.aether.artifact < plexus.core [DEBUG] Imported: org.eclipse.aether.collection < plexus.core [DEBUG] Imported: org.eclipse.aether.deployment < plexus.core [DEBUG] Imported: org.eclipse.aether.graph < plexus.core [DEBUG] Imported: org.eclipse.aether.impl < plexus.core [DEBUG] Imported: org.eclipse.aether.installation < plexus.core [DEBUG] Imported: org.eclipse.aether.internal.impl < plexus.core [DEBUG] Imported: org.eclipse.aether.metadata < plexus.core [DEBUG] Imported: org.eclipse.aether.repository < plexus.core [DEBUG] Imported: org.eclipse.aether.resolution < plexus.core [DEBUG] Imported: org.eclipse.aether.spi < plexus.core [DEBUG] Imported: org.eclipse.aether.transfer < plexus.core [DEBUG] Imported: org.eclipse.aether.version < plexus.core [DEBUG] Imported: org.slf4j.* < plexus.core [DEBUG] Imported: org.slf4j.helpers.* < plexus.core [DEBUG] Imported: org.slf4j.spi.* < plexus.core [DEBUG] Populating class realm maven.api [INFO] Error stacktraces are turned on.

我认为在客户操作系统和主机操作系统之间共享/home/vagrant/.m2/repository文件夹是一个问题，因为正在运行的/vagrant正常运行。

在这种情况下，Maven是否有理由不正确地阅读或解释用户settings.xml文件？

像往常一样，解释这个问题会让我走上寻找答案的道路。对于遇到这篇文章的人来说，问题是Chef Maven Cookbook有一个默认属性node['maven']['mavenrc']['opts']，它将/etc/mavenrc/的值设置为-Dmaven.repo.local=$HOME/.m2/repository -Xmx384m（从版本2.2.0开始）的食谱）。这覆盖了我在用户的settings.xml文件中执行的本地存储库的所有配置。

要解决此问题，我将配方的默认属性文件attributes/default.rb中的此属性的默认值更改为default[maven][mavenrc][opts] = ''

Maven忽略用户的settings.xml中的localRepository设置
