编译 java 文件时在 IntelliJ 项目上出现此错误。没有列出特定的源文件，但它失败并出现此错误。

删除以下编译器标志可修复错误：

-source 1.5 -target 1.5

但是，因为我们的目标是 Java 5，所以这些需要在那里。是否有一些特定的代码（可能是一个try/catch块）导致了这个错误？

当 try/finally 块出现在源代码中时，JSR/RET 指令出现在字节码中。即使使用 -target 1.5，Javac 1.6+ 似乎也不会发出它们，但 Eclipse java 编译器会。

例子

public class JSRDemo {
    public static void main(String[] args) {
        try {
            bodyOfTry();
        }
        finally {
            bodyOfFinally();
        }
    }

...

字节码

我今天收到了同样的错误：JSR/RET are not supported with computeFrames option

我发现，我正在commons-io为我的项目使用依赖项。

implementation 'commons-io:commons-io:2.11.0'

我根据 Gradle Suggestion 将此依赖项更新为最新版本。

implementation 'commons-io:commons-io:20030203.000550'

此更新版本导致错误！

我放回早期版本，错误消失了，构建成功！
