maven-compiler-plugin 编译失败：3.6.1

问题描述

我知道这里发布了很多 maven-compiler-plugin 失败问题。我阅读了其中的大部分内容，并尝试根据这些帖子中的解决方案解决我自己的问题。但这似乎不适用于我的情况。 这是我使用的：
Maven 版本：Apache Maven 3.6.2 (40f52333136460af0dc0d7232c0dc0bcf0d9e117; 2019-08-27T11:06:16-04:00)
Maven 主目录：C:\apps\apache-maven-3.6.2-bin\apache-maven-3.6.2\bin..
Java 版本：1.8.0_191，供应商：Oracle Corporation，运行时：C:\Program Files x86)\Java\jdk1.8.0_191\jre
默认语言环境：en_US，平台编码：Cp1252
操作系统名称：“windows 10”，版本：“10.0”，arch：“x86”，系列：“windows”

部分 pom.xml：

    <build>
        <sourceDirectory>src/main/java/com/xyz/shared</sourceDirectory>
        <plugins>
            <plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <configuration>
                    <includes>
                        <include>**/shared/**</include>
                    </includes>
                </configuration>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.6.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>

该项目在我的旧笔记本电脑（HP zbook）上编译时没有任何问题。 当我从命令行在另一台笔记本电脑（也是完全相同类型的 zbook）上运行相同的项目时， 喜欢

C:\workspace\xyz\common>mvn -e 干净编译

它显示了以下错误消息，

这里 maven 和 java 都是 32 位的。对于新旧笔记本电脑，它们是相同的。

我也尝试使用不同版本的 maven-compiler-plugin，但没有成功。

我不知道出了什么问题。

解决方法

发现问题了。 在父maven模块的pom.xml中，有一行

<executable>C:\Program Files (x86)\Java\jdk1.8.0_221\bin\javac.exe</executable>

这里的java版本与电脑上java的实际版本不同（jdk1.8.0_191）。将该行注释掉或更改为正确的 Java 版本可解决问题。
