Maven无法执行目标org.codehaus.mojo：exec-maven-plugin：1.3
嗨我使用maven编译一个jerseyweb服务项目，我在Windows 2008服务器中得到错误编译。
这是错误：

Apache Maven 3.2.1 (ea8b2b07643dbb1b84b6d16e1f08391b666bc1e9; 2014-02-15T01:37:52+08:00) Maven home: C:\apache-maven-3.2.1\bin\..

以下是Windows 2008中我的pom.xml的内容.pom.xml内容与mac略有不同。 （例如：java版本，：
4.0.0 org.company MyApplication jar 1.0-SNAPSHOT MyApplication org.glassfish.jersey jersey-bom ${jersey.version} pom import org.glassfish.jersey.containers jersey-container-grizzly2-http <!-- uncomment this to get JSON support: org.glassfish.jersey.media jersey-media-moxy --> junit junit 4.9 test com.google.code.gson gson 2.2.4 compile mysql mysql-connector-java 5.1.6 log4j log4j 1.2.17 org.apache.maven.plugins maven-compiler-plugin 3.1 true 1.8 1.8 true lib org.company.Main org.codehaus.mojo exec-maven-plugin 1.3 java org.company.Main 2.7 UTF-8
尝试先编译项目。 像以前一样运行命令，但稍作修改：
mvn -e compile exec:java
理由：当然我没有你的资源并且不能100％确定但是如果我在没有编译的情况下执行我会遇到同样的错误：
c:\standalone-jpa>mvn exec:java -Dexec.mainClass=tomczak.jpa.JpaTest [INFO] Scanning for projects...

然后，您应该再次运行您的命令：
mvn exec:java -Dexec.mainClass="your.Class"
对于我的情况，我安装了错误的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
