这个错误网上有很多种情况,但是我遇到的有两个:
第一种:进程占用;
这个错误是看同一个项目进程被占用,如果有的话,关闭就行。
第二种:pom文件资源配置有问题
<!-- 资源目录 -->
<resources>
<resource>
<!-- 设定主资源目录 -->
<directory>src/main/java</directory>
<!-- maven default生命周期,process-resources阶段执行maven-resources-plugin插件的resources目标处理主资源目下的资源文件时,只处理如下配置中包含的资源类型 -->
<includes>
<include>**/*.xml</include>
</includes>
<!-- maven default生命周期,process-resources阶段执行maven-resources-plugin插件的resources目标处理主资源目下的资源文件时,不处理如下配置中包含的资源类型(剔除下如下配置中包含的资源类型)-->
<excludes>
<exclude>**/*.yml</exclude>
</excludes>
<!-- maven default生命周期,process-resources阶段执行maven-resources-plugin插件的resources目标处理主资源目下的资源文件时,指定处理后的资源文件输出目录,默认是${build.outputDirectory}指定的目录-->
<!--<targetPath>${build.outputDirectory}</targetPath> -->
<!-- maven default生命周期,process-resources阶段执行maven-resources-plugin插件的resources目标处理主资源目下的资源文件时,是否对主资源目录开启资源过滤 -->
<filtering>true</filtering>
</resource>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.yml</include>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
</resources>
我出现的问题是第二种,没有配置src/main/resources这个目录的资源
