java - 编译 Maven 出现多个错误

Question

我正在尝试在我的项目中使用 maven，但每次都会收到此错误，并且不知道如何修复它。

以下是我的所有设置:

Java 版本:

C:\Users\TomBo\Downloads\AnimalShelterJavaGUI>java -version
java version "1.8.0_201"
Java(TM) SE Runtime Environment (build 1.8.0_201-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.201-b09, mixed mode)

Maven 版本:

C:\Users\TomBo\Downloads\AnimalShelterJavaGUI>mvn -v
Apache Maven 3.3.9 (bb52d8502b132ec0a5a3f4c09453c07478323dc5; 2015-11-

这是编译结果

我的JAVA_HOME目录:

我的 POM.xml 文件:

<groupId>groupId</groupId>
<artifactId>AnimalShelterJavaGUI</artifactId>
<version>1.0-SNAPSHOT</version>
<properties>
    <openfxVersion>11.0.2</openfxVersion>
    <codeVersion>11</codeVersion>

<build>
    <plugins>
        <plugin>

            </configuration>
        </plugin>
    </plugins>
</build>    

我想使用这个，因为我要和 Jenkins 一起工作。希望大家能帮帮我。

我猜您的 PATH 上的 JDK 错误，因为您的 java -version 显示 Java 8，而您尝试使用 Java 11 进行编译。

检查您的 PATH 变量。
