前言

版本信息：
idea 2020.1
Springboot 2.5.4
Maven 3.6.1

Maven编译报错如下：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:3.2.0:resources (default-resources) on project demo-case: Input length = 1 -> [Help 1]
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

解决

原pom.xml配置：

<build>
   <plugins>
      <plugin>
         <groupId>org.apache.maven.plugins</groupId>
         <artifactId>maven-compiler-plugin</artifactId>
         <configuration>
            <source>${java.version}</source>
            <target>${java.version}</target>
            <encoding>${project.build.sourceEncoding}</encoding>
         </configuration>
         <version>3.1</version>
      </plugin>
   </plugins>
</build>

改为：

<build>
   <plugins>
      <plugin>
         <groupId>org.apache.maven.plugins</groupId>
         <artifactId>maven-resources-plugin</artifactId>
         <version>2.7</version>
         <dependencies>
            <dependency>
               <groupId>org.apache.maven.shared</groupId>
               <artifactId>maven-filtering</artifactId>
               <version>1.3</version>
            </dependency>
         </dependencies>
      </plugin>
   </plugins>
</build>
