未能生成应用程序获取错误：：没有找到jdk类型的工具链

Question

我尝试过不同的解决方案，但对我来说没有用，

请查看错误日志和toolchain.xml文件。

这些是错误日志：

[INFO] --- maven-toolchains-plugin:1.1:toolchain (default) @ ad-api ---
[INFO] Required toolchain: jdk [ vendor='sun' version='1.8' ]

当我将版本1.8更新为jdk1.8._172时出现以上错误

下面是我的pom.xml

 <plugins>

   <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
   </plugin>

   <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-toolchains-plugin</artifactId>
      <executions>
         <execution>
            <goals>
               <goal>toolchain</goal>
            </goals>
         </execution>
      </executions>
      <configuration>
         <toolchains>
            <jdk>
               <version>jdk1.8.0_172</version>
               <vendor>sun</vendor>
            </jdk>
         </toolchains>
      </configuration>
   </plugin>

   <plugin>
      <artifactId>maven-resources-plugin</artifactId>
      <configuration>
         <encoding>${project.build.sourceEncoding}</encoding>
      </configuration>
   </plugin>

</plugins>

我已经在toolchain.xml中定义了jdk路径。

<toolchains>
    <toolchain>
    <type>jdk</type>
    <provides>
      <version>1.8</version>
      <vendor>sun</vendor>
    </provides>
    <configuration>
      <jdkHome>C:\Program Files\Java\jdk1.8.0_172</jdkHome>
    </configuration>
  </toolchain>
</toolchains>

请帮助解决问题的地方。提前谢谢。

将pom中的版本更改为1.8而不是jdk1.8.0_172

                <configuration>
                    <toolchains>
                        <jdk>
                            <version>1.8</version>
                            <vendor>sun</vendor>
                        </jdk>
                    </toolchains>
                </configuration>

仔细检查您的目录路径。关于文件位置和使用maven --toolchains C:\User\zzz\.m2\toolchains.xml clean install进行测试的两条评论帮助我看到，我的文件夹是"m2“而不是".m2”。
