m2e error in MavenArchiver.getManifest()

Question

I am seeing an error in my STS and am not sure how to debug it. Searching around I only see vague references to the error and no solutions.

The error is:

org.apache.maven.archiver.MavenArchiver.getManifest(org.apache.maven.project.MavenProject, org.apache.maven.archiver.MavenArchiveConfiguration) pom.xml /<maven projectName> line 1 Maven Configuration Problem

Question: Can anyone give any suggestions on how to get more information on the issue in order to debug it further or any possible solutions?

Maybe some more context on what the functionality of method is. The javadoc associated with the MavenArchiver.getManifest() method is not very detailed and there is no stack trace that I see. I've tried several refreshes and updates of the project and associated projects including clearing my local m2 repo.

STS info:

• Version: 3.7.3.RELEASE
• Build Id: 201602250940
• Platform: Eclipse Mars.2 (4.5.2)

m2e info:

• Version: 1.6.2.20150902-0002

I had the same problem with a spring boot project. the solution was to downgrade the jar maven-jar-plugin from 3.2 to 2.6 . i had just to add this to the project pom:

<properties>        
    <maven-jar-plugin.version>2.6</maven-jar-plugin.version>
</properties>

I had the same problem with a spring boot project. The solution was to downgrade the spring-boot-starter-parent dependency version from 2.0.0.RELEASE to 1.5.10.RELEASE(you can move to any stable version)

from:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.0.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

to

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.10.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

I had also faced the same issue and it got resolved by changing the version from 3.2.0 to 2.6 as shown in below pom.xml snippet

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.6</version>
    <configuration>
        <warSourceDirectory>src/main/webapp</warSourceDirectory>
        <warName>Spring4MVC</warName>
        <failOnMissingWebXml>false</failOnMissingWebXml>
    </configuration>
</plugin>
