Maven构建在ubuntu流浪者机器以及docker实例内部失败 [英] maven builds fails inside ubuntu vagrant machine as well as docker instance

问题描述

我正在使用jaxb开发一个api. Maven构建(使用jdk-7)可在我的本地Windows计算机上使用.现在，如果在vm上设置了maven和openjdk7之后，尝试在流浪者的盒子(ubuntu/trusty64)上构建它，则在执行mvn全新安装时会出现以下错误:

I am developing an api using jaxb. The maven build (using jdk-7) works on my local windows machine. Now if I try to build it on my vagrant box (ubuntu/trusty64) after setting up maven and openjdk7 on the vm, I get following error on performing mvn clean install:

java.io.FileNotFoundException(不允许操作)

java.io.FileNotFoundException (operation not permitted)

在我的pom.xml中，所有5个项目中都有一个，成功构建了前3个(业务和项目)，只有第4个(生成战争)文件在尝试生成时失败，并显示此错误战争档案. Maven成功将其他文件复制到其他项目的目标文件夹中.

There are in all 5 projects as part of my pom.xml, the first 3 (business and projects) gets built successfully, only the 4th one (which generates the war) file fails with this error when it is trying to generate the war file. Maven was successful in copying other files into the target folder for other projects.

此外，我能够在同一台机器上执行maven构建，而在简单的Java项目上没有错误(来自

Also, I am able to do perform maven builds on the same machine without errors on simple java projects (from https://maven.apache.org/guides/getting-started/maven-in-five-minutes.html)

我的猜测是，Vagrant Virtualbox VM不能将所需的资源分配给JVM，但是我对如何做到这一点一无所知.我确实尝试通过在vm上设置Maven属性来增加内存占用

My guess is the Vagrant Virtualbox VM is not is not able to allocate required resources to JVM but i am clueless on how i could do it. I did try to increase the memory footprint by setting the maven properties on my vm

export MAVEN_OPTS =-Xms1024m -Xmx4096m -XX:PermSize = 1024m"

export MAVEN_OPTS="-Xms1024m -Xmx4096m -XX:PermSize=1024m"

推荐答案

似乎您没有写该文件夹的权限. 您可以尝试使用chmod 777. -R在无业游民的共享文件夹中.同样，在执行此操作之前，您可以检查是否可以通过"touch target/newFile"在目标目录中创建新文件.

it seems that you don't have permision to write in that folder. you could try using chmod 777 . -R in the vagrant shared folder. Also before doing this you could check if you can create a new file in the target directory by "touch target/newFile".
