META-INF/versions/9/module-info.class: broken class file? (This feature requires ASM6)

早过忘川 提交于 2020-12-30 05:34:19
问题 I'm having issues with Bouncycastle, which only arise when running the :lint task. Generally it seems to be a Java 9 byte-code version 53.0 / ASM version conflict. These are the dependencies: // https://mvnrepository.com/artifact/org.bouncycastle implementation "org.bouncycastle:bcprov-jdk15on:1.64" implementation "org.bouncycastle:bcpkix-jdk15on:1.64" Which cause the :lint task to throw processing errors: > Task :mobile:lint Error processing bcpkix-jdk15on-1.64.jar:META-INF/versions/9/module

How do I map ASM's API version in Opcodes to Java version?

旧街凉风 提交于 2020-12-26 04:30:10
问题 ASM's ClassVisitor constructor requires passing one of Opcodes's ASM4, ASM5, ASM6, ASM7, ASM8 or ASM9. How do I know which ASM# to use for each version of Java? What ASM# would I use for Java 8? What ASM# would I use for Java 11? 回答1: The ASM… constants describe the minimum ASM library version required by your software. This is crucial for compatibility, e.g. in the Visitor API, as when you’re overriding a method that does not exist in an older version, you wouldn’t notice when linking

How to read a Java class method annotation value with ASM

时光总嘲笑我的痴心妄想 提交于 2020-12-12 04:31:26
问题 How can I read read the value of a Java method annotation at runtime with ASM ? The Annotation has only a CLASS RetentionPolicy , so it's not possible to do that with Reflections. | Policy CLASS : Annotations are to be recorded in the class file by the compiler but need not be retained by the VM at run time Example : I want to extract the value Carly Rae Jepsen out of the artist field at runtime: public class SampleClass { @MyAnnotation(artist = "Carly Rae Jepsen") public void callMeMaybe(){}

Debugging ASM-generated bytecode with JDB (or similar)

半世苍凉 提交于 2020-12-01 11:54:28
问题 So I have some malfuctioning code to debug where SOMEthing throws an NPE and I'd like to step through some generated methods in order to try and find out why. Except stepping blindly is not really useful. Thread-4[1] list Source file not found: Foo.java Thread-4[1] locals Local variable information not available. Compile with -g to generate variable information The code was generated, so of course there is no .java file available for JDB. And since I don't compile it with javac, there's no
