Intellij Idea 13.x and ASM 5.x library incompatible?

问题

I can't get Intellij Idea 13.0 to compile my code against ASM 5.0.3

I have a multi-module Maven project. It compiles and installs successfully.

Apparently com.google.findbugs:findbugs has a dependency on asm:asm:3.3 and I want to use org.ow2.asm:asm:5.0.3 to manipulate some bytecode.

So in the parent pom.xml I exclude the asm:asm:3.3 dependencies from the classpath. This works fine when I run mvn install from the command line.

I can't get the Build -> Make Project menu selection to work in Intellij Idea.

Here is the relevant parts of my pom.xml files.

parent.pom

<dependency>
    <groupId>org.ow2.asm</groupId>
    <artifactId>asm</artifactId>
    <version>5.0.3</version>

</dependency>


<dependency>

    <artifactId>findbugs</artifactId>

    <exclusions>
        <exclusion>
            <groupId>asm</groupId>
            <artifactId>asm</artifactId>
        </exclusion>
        <exclusion>
            <groupId>asm</groupId>

        </exclusion>
        <exclusion>
            <groupId>asm</groupId>
            <artifactId>asm-tree</artifactId>
        </exclusion>
    </exclusions>
</dependency>

Here is the code that is failing

18       public static void main(final String[] args) throws IOException 
19       { 
20           final InputStream is = NotEmptyTest.class.getResourceAsStream("/com/vertigrated/annotation/NotEmptyTest.class"); 
21           final ClassReader cr = new ClassReader(is); 
22           final ClassNode cn = new ClassNode(); 
23           cr.accept(cn, 0); 
24           for (final MethodNode mn : cn.methods)
25           { 
26 - 38 snipped for brevity 
39           } 
40       } 
41   }

Here is the error message:

Information:Using javac 1.7.0_25 to compile java sources
Information:java: Errors occurred while compiling module 'tests'
Information:Compilation completed with 1 error and 2 warnings in 2 sec

As you can see in the screen capture, it reports the correct version of the libraries in the Javadoc but the AutoComplete shows the old `3.3` non-typesafe return value of `List` instead of `List<MethodNode>`:

Here is what Maven knows, which is correct:

How do I get Intellij Idea to use the correct dependency internally?

回答1:

It looks like you end up having asm-5.0.3.jar in your compilation class path in IntelliJ IDEA. This JAR is optimized for minimal size by stripping every bit of it that could be stripped, including the generic signatures (that's how a List<MethodNode> becomes a List, which is effectively List<Object> in your case).

To make sure this is the case, try replacing the dependencies on asm, asm-tree etc by asm-debug-all. The JAR you get will be bigger, but the project should compile now.

Next question is how this compiles in mvn, but fails in IntelliJ IDEA. You can see the class path in the "Project Structure" dialog under "Modules", on the "Dependencies" tab. Maybe the class path was not imported correctly in IntelliJ (in that case, report to IntelliJ IDEA's issue tracker, you'll probably get some help rather soon).
