Error when running Spring boot application with Maven: Name for parameter binding must not be null

My Spring boot application using Spring boot 1.5.12 and Java 8 executes perfectly fine in my development environment, but when deploying to testing environment, I'm facing difficulties:

I start the application with : mvn spring-boot:run and the execution stops with an error:

java.lang.IllegalArgumentException: Name for parameter binding must not be null or empty! On JDKs < 8, you need to use @Param for named parameters, on JDK 8 or better, be sure to compile with -parameters.

I did some searches and understand that in order that my repositories methods work, like this one:

@RepositoryRestResource(collectionResourceRel = "users", path = "users")
public interface UserRepository extends JpaRepository<User, Long>, UserRepositoryCustom {

    @Query("SELECT u FROM User u WHERE u.primaryEmail.emailAddress = :emailAddress "
            + "AND u.deleted = 0")
    Optional<User> findByPrimaryEmailAddress(String emailAddress);

I need to compile with the "-parameters" option, because I don't put the @Param annotation on the paremeter "emailAddress".

It works in Eclipse since there is an option activated for the compiler, but when I use maven to compile the app outside of Eclipse, the option must be set.

My problem is that in Spring boot documentation, and since I'm using the default spring-boot-maven-plugin in my pom.xml

    <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
    </plugin>

it should manage this compiler option automatically, and it seems it doesn't.

When I compare the spring-boot-starter-parent-1.5.12.RELEASE.pom and the pom of the latest version of spring boot on github, I cannot see on my 1.5.12 version the 

<parameters>true</parameters>

Do you have any idea of how I can fix my issue?

I will try to replace the spring-boot-maven-plugin with maven-compiler-plugin with the "-parameters" compiler arg, but I would be more confident if I could use the default spring-boot-maven-plugin.

Thank you!

I think that the option "-parameters" in spring-boot-maven-plugin" has probably been added recently, and the documentation is not correct for Spring boot 1.5.12 (maybe it is for Spring boot 2.0.0)

I resolved the issue by configuring myself the maven compiler:

    <plugin>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
            <source>${java.version}</source>
            <target>${java.version}</target>
            <compilerArgs>
                <arg>-parameters</arg>
            </compilerArgs>
        </configuration>
    </plugin>

Important: the "-parameters" arg must be set

You need parameter for emailAddress, jpql cant understand what parameter is given.

Optional<User> findByPrimaryEmailAddress(@Param("emailAddress") String emailAddress);

Try with that!
