我的 Maven 存储库位于./java目录中。我想在./java目录中运行 Maven 测试，但出现以下错误：
The goal you specified requires a project to execute but there is no POM in this directory (/github/workspace). Please verify you invoked Maven from the correct directory. -> [Help 1]
这是我的工作流程：

- …我1.c使用调试信息进行编译：
gcc -O0 -g ./1.c\n// 1.c\n#include <stdio.h>\n#include <string.h>\nint main() {\n char c[222];\n scanf("%s", c);\n int a = strlen("dadw");\n return 0;\n}\n但我找不到strlen通过readelf -a a.out或nm ./a.out。根据我的理解，strlen是由动态链接提供libc.so并解决的。所以它应该出现在符号表中。难道是gcc的一些特殊trick造成的？
