我正在尝试运行我的JSQL解析器类,但我得到了Error: java: invalid source release 1.9.

我试着按照这个答案.我更改了文件>构建,执行,部署> Java编译器>项目字节码版本:1.8.但是,我无法将模块语言级别和项目语言级别更改为1.8,因为没有选项.我仍然在下面得到同样的错误.

错误

package cs4321.project2;

import java.io.FileReader;
import net.sf.jsqlparser.parser.CCJSqlParser;
import net.sf.jsqlparser.statement.Statement;

    public static void main(String[] args) {

我有一个简单的Maven项目:

src
??? main
    ??? java
        ??? module-info.java
pom.xml

pom.xml中:

<groupId>org.example</groupId>
<artifactId>example</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>jar</packaging>
<name>example</name>

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.7.0</version>
            <configuration>
                <release>10</release>
            </configuration>
        </plugin>
    </plugins>
</build>

当我通过构建项目时mvn -X install -DskipTests=true,它失败了:
