Answer 1

尝试修改下要编译文件中的pom.xml的“maven-compiler-plugin”
修改成
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.3</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
试一下，1.7则是java的版本，还需要注意mvn调用的java是否和环境中的java相同

Answer 2

需要配置jdk环境变量 classpath和JAVA_HOME

Answer 3

兄台，此问题困扰我很久，请问你解决了吗，也是maven编译打war包时报的错，如果解决了，还请赐教，谢谢了！

Answer 4

<bootclasspath>${java.home}/lib/rt.jar;${java.home}/lib/jce.jar</bootclasspath>

window下是分号 linux 是冒号
如果帮到你 请关注下我的公众号，里面可以在线问我 公众号是JAVA思考者
