Java Compiler Version for Maven Spring Boot Product Build

Question

Here , it says that Spring Boot 1.5.2.RELEASE requires Java 7 or later; and Java 1.6 as the default compiler level.

So will this difference cause a problem?

Answer 1

You can specify the JDK to build Maven using the following plugin;

Apache Maven compiler plugin .

<project>
  ...
  <build>
    <pluginManagement>
      <plugins>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-compiler-plugin</artifactId>
          <version>3.6.1</version>
          <configuration>
            <source>1.7</source>
            <target>1.7</target>
          </configuration>
        </plugin>
      </plugins>
    </pluginManagement>
  </build>
  ...
</project>

Trying to compile Java1.7 code with JDK 1.6 will really cause problems.

You can also use the property java.versionto indicate your version of Java, as described here , you can see the usage maven-compiler-pluginin spring-boot-parentpom.xml, here
