maven-resources-plugin needs to be modified to version 3.1.0 to solve the problem

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>3.1.0</version>
</plugin>

Please can you provide a sample project that shows the problem?

There's no mvn branch on GitHub. Did you push it?

Sorry, I accidentally deleted it. Now it has been pushed up

Comment From: snicoll

@brucelwl thank you for the sample. application.properties contains non UTF-8 characters. I've removed those comments and this doesn't fail for me anymore. Spring Boot uses UTF-8 by default when you use spring-boot-starter-parent but that's something you can easily override for your own need.

It looks like the previous of the plugin tolerated those non UTF-8 character when filtering and does not anymore. If you think there's a regression in the ressources plugin, please follow-up on their issue tracker.

Comment From: brucelwl

@snicoll @philwebb thank you very much for solving my question

Comment From: ancchi

Hi, I'm new to Maven and Id didn't get the solution, yet. Did I miss it? Whenever I write something into my application.properties (even if it's only a normal letter) that bug appears. It's about the UTF-8 Encoding, that's for sure, but how do I fix it? In the end I changed my Java-Version from 11 to 8 and the maven-version from 2.4.1 to 2.3.7. Now it works but that cannot be the solution? Thx in advance!

Comment From: snicoll

@ancchi sorry but we can't give you Maven support here. Please follow-up on StackOverflow or file an issue in for the maven-resources-plugin project. I've shared the link to it in my previous comment.

Comment From: katriel18

I solve the error by eliminating any word that has a "ñ" from my "application.properties" file that caused me the error when deploying my project.

Comment From: dimitrycastex

same here, i delete the "ó" letter in a comment from my .properties file and problem solved.

Comment From: xzharkonx

Yes, i have in my .properties file comments with accents in my words because i speak spanish, the solution is remove them, then will run for complete. Saludos desde México Cabrones!, si se pudo! xD

Comment From: tommai78101

My other option is to add this to the <project> in the pom.xml file:

<build>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-resources-plugin</artifactId>
        <version>3.2.0</version>
        <!-- Add the following exclusions here. -->
        <configuration>
            <nonFilteredFileExtensions>
                <nonFilteredFileExtension>properties</nonFilteredFileExtension>
            </nonFilteredFileExtensions>
        </configuration>
    </plugin>
</build>

Comment From: haroldo-ok

Thanks for the pointers, though it would certainly be far easier to fix such errors if the tool simply gave a message saying that a certain file contains invalid characters...

Comment From: davidddp

In my case, they were the file accents: messages_en.properties

Comment From: hmyenilmez24

I have deleted "ç" letter in the comment line on application.properties file and it worked..

Comment From: ybinds

Nothing seems to work for me

Comment From: ybinds

I added the plugin as suggested above as well, still it fails. I am not sure how to fix this, any help is much appreciated. There is nothing in application.properties file to clean

Comment From: philwebb

@ybinds The "requires Maven version 3.2.5" error suggests that you're Maven version is old. Please try upgrading it and checking with mvn --version.

Comment From: ybinds

I see that, but do I install a specific version of Maven? Any guidance please? On my instance when I say sudo yum install maven, it is installing 3.0.5 version

Comment From: ybinds

Ok I could fix my issue. I just have to remove the existing version and put a latest version 3.8.6.

Comment From: rahulcse03

In my case we have a keystore certificate file, so cant change anything in there. Here is what i did, excluded that file (sample.jks) from checks and it worked :

            <testResource>
                <filtering>true</filtering>
                <directory>src/test/resources</directory>
                <excludes>
                    <exclude>sample.jks</exclude>
                </excludes>
            </testResource>

Comment From: rugratz24

try changing your file properties to "create and delete files" this method works on me

Comment From: dansousac2

I have deleted "ç" letter in the comment line on application.properties file and it worked..

Thanks, well as i thought -> must remove from COMMENTARIES(#) on application.properties non-utf8 chars

Comment From: DalthonMike

No meu application.properties existiam alguns comentários, e nesses comentários existiam caracteres especiais. Ao retirar os caracteres especiais cheguei na solução para o meu problema.

Exemplo:

Antes

// Configurações do JPA/Hibernate spring.jpa.show-sql=true spring.jpa.hibernate.ddl-auto=create-drop spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.H2Dialect spring.sql.init.mode=always

Depois:

// Config do JPA/Hibernate spring.jpa.show-sql=true spring.jpa.hibernate.ddl-auto=create-drop spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.H2Dialect spring.sql.init.mode=always
