It is problem that is mostly occurring in eclipse IDE only. This is scheduled to fix in later version but not sure when.

To resolve this you can add a property to update the maven jar plugin in pom.xml.

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

Once you edit the pom.xml, just do an update to your spring boot application. Right click on Springboot Application>>Maven>>update project.

The error sign from your pom.xml will go away.

There is incompatibilities between the version of M2E and the version 3.1.2 of the maven-jar-plugin.

Until the problem is solved by the development teams of M2E or maven-jar-plugins, you have to add in your pom.xml file the following line in order to solve this issue:

<build>
<pluginManagement>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <version>3.1.1</version>
        </plugin>
    </plugins>
</pluginManagement>
</build>

Please update tag in porm.xml

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
     <maven-jar-plugin.version>3.1.1</maven-jar-plugin.version>
</properties>

This happening with 2.1.5.RELEASE. Add the following entry to your pom to fix that issue.

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

Why does change from Spring boot version 2.1.4 to 2.1.5 gives unknown configuration Maven error?
