Maven projects depend on a fixed JDK version

Previous Article Creating a Maven Multi-Module Project with    Eclipse

The project structure is shown in the figure

jre uses 1.5 I use 1.7 to modify

 

 

Right click on the project hill --> Properties

 

 

Check out the project after completion

 
It's already 1.7

But is it over?

 

Now I remove the project and re-import it to see if it is still 1.7

 After re-importing it changed back. Is it difficult to change it again?

Now I'm going with a once-and-for-all approach.

 

I added the following code to the pom.xml of zwp-parent:

<build>
    <plugins>  
        <plugin>  
            <groupId>org.apache.maven.plugins</groupId>  
            <artifactId>maven-compiler-plugin</artifactId>  
            <version>3.5.1</version>
            <configuration>  
                <source>1.7</source>  
                <target>1.7</target>
                <skip>true</skip>
            </configuration>  
        </plugin>
    </plugins>  
  </build>

 


 

Then remove the project and re-import it.
