maven2 up to maven3的'version' contains an expression but should be a constant 

 

 

这个更改为常量即可重新编译了。

 

今天遇到个问题，连接池的一直连接不到，最后重新尝试了一下代码的，结果证明是连接访问权限问题。

连接访问权限问题。

结论如下：

 

 

问题排查：一个错误引起的pom 异常，进而引起 jar 失败。

重点就在这一行，所以通过刚刚的翻译由此可知，这个 version 标签里面不能使用表达式；必须是一个具体的版本号才行；执行这个命令后，就会将所有依赖的地方全部变成新的版本号，且会在每个子module工程中生成一个名为。将version 标签内容改为一个具体的版本即可，只要不带。是将 version 标签的内容改为了具体的版本号。变更版本号需要使用maven插件执行以下命令，新公司，一个项目进行二次开发，使用。知道问题在哪了，那就着手解决吧！内容是一样，只是有一点不同，的文件，这个文件和原来的。

在maven工程中pom.xml引用依赖报错：spring-core:jar must be a valid version but is '${spring.version}'。 因为maven不知道你引用的jar包的版本，导致无法获取这个jar，所以你必须指定一个版本号。${spring.version}是引用的一个变量，而这个变量你没有在pom.xml里声明，所以报错。
