如果依赖一直添加不到idea的external libraries中，可以参考下列几个命令：

复制代码

# 1. 先清理所有
mvn clean

# 2. 强制更新所有依赖
mvn dependency:sources

# 3. 或者使用离线模式先下载
mvn dependency:go-offline

# 4. 重新编译
mvn compile -U

# 5. 重新生成Wrapper文件，指定maven版本
mvnw wrapper:wrapper -Dmaven=3.9.12
# 或
mvn wrapper:wrapper -Dmaven=3.9.12

# 6.清理idea的缓存
mvnw.cmd -U clean

# 7. 查看项目使用的mvn和jdk版本，在项目根目录执行
./mvnw -v  # Windows: mvnw.cmd -v

如果还是不行，可以删除项目下的idea文件，重新打开，然后编译compile 和 install试一下
