[英]Check if library will work on a specific verion of Java
What approach can be taken to verify that a library is compatible on a specific version of Java? 可以采用什么方法来验证库是否与特定版本的Java兼容?
Example: Library X was compiled on Java 1.7, therefor it might not work on Java 1.7 or lower. 示例:库X是在Java 1.7上编译的,因此它可能无法在Java 1.7或更低版本上运行。
Thank you. 谢谢。
The best is to check the byte code via an enforcer rule which can be applied to your build by using the maven-enforcer-plugin ... 最好的方法是通过强制规则检查字节代码,该规则可以通过使用maven-enforcer-plugin应用于您的构建...

compile with the version you want: 使用您想要的版本进行编译:
javac -target ...
see that: How do i compile a .java with support for older versions of java? 看到: 我如何编译支持旧版Java的.java?
and check jar dependencies: with Jdepend for example 并检查jar依赖项:例如使用Jdepend
