我正在使用maven编译一个球衣web服务项目，并在Windows 2008服务器中编译错误。
这是错误：

这是我的maven和java版本：

首先尝试编译项目。像以前一样运行您的命令，但稍作修改：
mvn -e compile exec:java
理由： 当然，我没有你的资源，也不能100％肯定，但如果我先执行而不先编译，我会遇到同样的错误：
c:\standalone-jpa>mvn exec:java -Dexec.mainClass=tomczak.jpa.JpaTest

然后，您应该再次运行命令：
mvn exec:java -Dexec.mainClass="your.Class"
答案 1 :(得分：0)
就我而言，我安装了错误npm 版本。我需要7.6为我的依赖，但我有3.6。
我删除并安装了npm到最新版本：
sudo apt-get remove npm && sudo apt-get autoremove
curl -sL https://deb.nodesource.com/setup_7.x | sudo -E bash -
sudo apt-get install -y nodejs
sudo apt-get install -y build-essential
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.1/install.sh | bash
source ~/.bashrc
nvm install 7.6
nvm use 7
