javac Task Error source release 1.7 requires target release

The following error occurred while compiling Java code using IDEA:
Error: Java: javacTask: source release 1.7 requires target release 1.7
Above:

When such a problem occurs, you can set it in Settings:

Just set the compiler version to 1.7 here. The first place is where the project is set and the second place is where the module is set.

To build with Maven, specify the compiled version of Java directly in the POM, adding the following code:

    <build>
        <finalName>5_mybatis_maven</finalName>
        <plugins>
            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.7</source>
                    <target>1.7</target>
                </configuration>
            </plugin>
        </plugins>
    </build>

Then select pom.xml and right click, and Reimport will tell Maven to download the corresponding plug-in:


Now to compile, is not to see the rainbow in the wind and rain!

, I always thought it was

ERROR – #org.jetbrains. Idea. maven. maven. Cannot reconnect.

maven has a problem, re-import, still not fixed.

later found:

Caused by: java.net.ConnectException: Connection timed out: connect

just remembered the problem of firewall.

close firewall

find: control panel \ all control panel items \Windows Defender firewall \ custom Settings

check off:

restart, and it’s ok ~~~

About solving the problem that vscode files cannot be edited

many times when we use VSCode to open a file sent by someone else or modify a configuration file, we will find that the file cannot be modified.

does not mean that files cannot be modified, but VSCode editing adopts the mode similar to Vim editor. Only when you type I can you modify. After the modification is completed, you can type Command+S(MacOS) or Control+S(Windows) is unable to save.

detailed usage of the vim editor can be seen in [MIT open class (a missing lesson in computer education)]3. Editor (Vim).
