maven - JDK7，mvn-3.2.2 - maven-enforcer-plugin - RequireJavaVersion 失败

Question

我正在使用 JDK 1.7.0_60 和 maven-3.2.2。当我在项目 new-project 上运行 mvn clean install 时，出现以下错误 -

[INFO] --- maven-clean-plugin:2.5:clean (default-clean) @ new-project ---

如果您想将版本 1.7.0-30 包含在已接受的 range 中，那么在声明范围时必须使用方括号。您可以省略版本 1.6，因为它包含在该范围内:

<requireJavaVersion>
    <version>[1.5,1.7.0-60]</version>
</requireJavaVersion>
