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>

[philwebb]

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

[philwebb]

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

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

[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.

[brucelwl]

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

[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.

[dimitrycastex]

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

[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

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>

[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...

[davidddp]

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

[hmyenilmez24]

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

[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>

[rugratz24]

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

[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

[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
