Maven clean install: Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:3.2.0:resources

I don´t know what´s the problem. Trying to install maven for a college project. I already installed maven as instructed here. Picture Environmental Variables, maven version in cmd And I also tried to delete the .m2 file. When I try to install maven over the plugin in InteliJ, I get the message: "process terminated" with no extra info. Then I tried to install over the terminal with mvn clean install and i got this.

I honestly have no clue what it is telling me. Is it because there is something wrong with my pom.xml? Pls help me! Thank you in advance.

Edit: I used the spring boot intitializer to create the project.

Solution 1:

It might be a new bug coming with some latest release of Spring-boot (and then : Spring).

I had it. The workaround is to put in your pom.xml this corrected dependency :

<!-- Pour contourner un bug à la génération par Spring-boot 2.4.x : 
Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:3.2.0:resources (default-resources) on project application-etude: Input length = 1 -->               
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>3.1.0</version>
</plugin>               

Solution 2:

The root cause of the exception is that some resources contain resources which should not filtered (aka binary). The correct solution is to define an exclude for file extensions which should not filtered like the following:

<project>
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>

          <nonFilteredFileExtensions>
            <nonFilteredFileExtension>pdf</nonFilteredFileExtension>
            <nonFilteredFileExtension>swf</nonFilteredFileExtension>
          </nonFilteredFileExtensions>
        </configuration>
      </plugin>
    </plugins>
