为什么Springs自动生成的pom文件不可解析？

Question

I've been trying to setup a spring websocket server using the stat.spring.io generator which generates a pom file etc.

It seems that the generated pomfile is unparsable for some reason and i've spent hours trying to fix it.

I've tried using Java 1.7 with spring 2. . to no avail.

Please can someone help explain why it might not be parsing:

Here is my full pomfile:

Answer 1

The pom.xml you have posted is not valid XML. it is missing a closing tag for project as mentioned above. Also, you mention using java 1.7 with spring 2.

https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.0-Release-Notes#java-8-baseline-and-java-9-support states:

Spring Boot 2.0 requires Java 8 as a minimum version.

I checked your XMl by pasting it here: https://www.xmlvalidation.com/index.php?id=1&L=0 you may wish to have that check pass first.
