maven-compiler-plugin 編譯失敗：3.6.1

Question

我知道這里發布了很多 maven-compiler-plugin 失敗問題。 我閱讀了其中的大部分內容，並嘗試根據這些帖子中的解決方案來解決我自己的問題。 但這似乎不適用於我的情況。 這是我使用的：
Maven version: Apache Maven 3.6.2 (40f52333136460af0dc0d7232c0dc0bcf0d9e117; 2019-08-27T11:06:16-04:00)
Maven 主頁：C:\apps\apache-maven-3.6.2-bin\apache-maven-3.6.2\bin..
Java 版本：1.8.0_191，供應商：Oracle Corporation，運行時：C:\Program Files x86)\Java
默認語言環境：en_US，平台編碼：Cp1252
操作系統名稱：“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>

該項目在我的舊筆記本電腦（HP zbook）上編譯沒有任何問題。 當我從命令行在另一台筆記本電腦（也是相同類型的 zbook）上運行相同的項目時，例如

C:\workspace\xyz\common>mvn -e clean 編譯

它顯示了以下錯誤消息，

這里 maven 和 java 都是 32 位。 對於新舊筆記本電腦，它們是相同的。

我還嘗試使用不同版本的 maven-compiler-plugin，但沒有運氣。

我不知道出了什么問題。

Answer 1

問題找到了。 在父maven模塊的pom.xml中有一行

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

這里的 java 版本與電腦上 java 的實際版本不同（jdk1.8.0_191）。 注釋掉該行或更改為正確的 java 版本修復該問題。
