Question

当我完成我的应用程序并将其导出到其他计算机时，我正在尝试创建我的可执行jar。但是，我得到指示的错误。有什么建议吗？

我已经按照POM尝试了具有依赖性和阴影的Jar

details:=[][]string{}
for rows.Next() {
    cols := make([]string, num_cols)
    // Create an array of string pointers pointing to the column strings.
    col_ptrs = make([]*string, num_cols)
    for i := 0; i < num_cols; i++ {
        col_ptrs[i] = &cols[i];
    }
    rows.Scan(col_ptrs...)
    details = append(details, cols)
}

例外：
