You seem to be running under Windows, not LINUX/UNIX. The path separator on Windows is ;, not :. Additionally, you haven't put you jar file in the classpath. So what you want is:
您似乎是在 Windows 下运行，而不是在 LINUX/UNIX 下运行。Windows 上的路径分隔符是;, 不是:。此外，您还没有将 jar 文件放在类路径中。所以你想要的是：
java -cp aJar.jar;junit-4.10.jar org.junit.runner.JUnitCore TestOne
This of course assumes that both jars are in the current directory. You should also always avoid putting classes in the default package.
这当然假设两个 jars 都在当前目录中。您还应该始终避免将类放在默认包中。

I had recently the same problem (JUnit 4.12) and I managed to solve it (Windows) by the following command:
我最近遇到了同样的问题（JUnit 4.12），我设法通过以下命令解决了它（Windows）：
java -cp "<libs>;<relative path to .class project folder>" org.junit.runner.JUnitCore <package.ClassName>
Import to notice the "" in the classpath declaration and separated by ";"
导入以注意类路径声明中的“”并以“;”分隔
