我正在使用Emma代码覆盖率工具，并且具有Java8。我是Emma的新手，几乎没有可用的帮助。我试图使用以下链接。
http://emma.sourceforge.net/intro.html
http://users.csc.calpoly.edu/~jdalbey/309/Lectures/emmademo.html
但是当我尝试运行时，我一直收到以下错误：
java -cp emma.jar emmarun -jar .../jdk1.4.2/demo/jfc/SwingSet2/SwingSet2.jar
java -cp TestTools\emma.jar;. emmarun -cp . CircleConverter
我也尝试了here中的选项，但没有帮助。
错误是-
CoverageDemo>java -XX:-UseSplitVerifier -cp TestTools\emma.jar;. emmarun -cp . CircleConverter
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option UseSplitVerifier; support was removed in 8.0

Exception Details:
最佳答案
实际上，问题是由于以下这一行：
Caused by: java.lang.VerifyError: Expecting a stackmap frame at branch target 11
我通过以下链接找到了解决方案：java.lang.VerifyError: Expecting a stackmap frame at branch target JDK 1.7
但是简而言之，java7引入了更严格的验证，并且要禁用它，如果您使用的是java7，我们可以添加选项“ -XX：-UseSplitVerifier”，如果您使用的是java8，则可以添加“ -noverify”。
因此，java8的正确命令行为：
java -noverify -cp emma.jar emmarun -jar .../jdk1.4.2/demo/jfc/SwingSet2/SwingSet2.jar
