The unknown errors occur in pom.xml when using STS4

Introduction

I start I made the new spring starter project in sts4.

But I checked the unknown error in pom.xml.

Subject

Why do these errors occur?

When the spring framework builds and compiles, depend on maven.

Something went wrong here and there was an error.

I don't know the specific reason.

How do fix these error?

Default pom.xml exists the only java.version in <properties>.

Add maven version 3.1.1 in <properties>.

<properties>
	<java.version>1.8</java.version>
	<maven-jar-plugin.version>3.1.1</maven-jar-plugin.version>
</properties>

Conclusion

IDE configuration is very important.

I hope it will help people who have the same problem as me.
