distributed-redis-tool

distributed-redis-tool copied to clipboard

Hi, in distributed-redis-tool-1.0.5, there are mulptiple versions of library org.springframework:spring-core. However, according to Maven's dependency management strategy: "first declaration wins", only org.springframework:spring-core:4.2.1.RELEASE can be loaded, and org.springframework:spring-core:4.3.10.RELEASE will be shadowed.

In total, there are 21 conflicting API pairs between these two library version.

As shown in the following figure, your project expects to invoke method <org.springframework.asm.Handle: toString()Ljava/lang/String;> in library org.springframework:spring-core:4.3.10.RELEASE (along the original dependency path). As it has been shadowed, this method defined in org.springframework:spring-core:4.2.1.RELEASE is actually forced to be referenced via the following invocation path (along the actual dependency path):

<org.springframework.asm.Handle: toString()Ljava/lang/String;>

Although both of these conflicting libraries contain the referenced methods (with the same signature), they have different implementations. This issue will not cause runtime crashes, but it can introduce inconsistent semantic program hehaviors----

Code snippet of <org.springframework.asm.Handle: toString()Ljava/lang/String;> in org.springframework:spring-core:4.3.10.RELEASE (shadowed but expected to invoke method):

public String toString() {
        return owner + '.' + name + desc + " (" + tag + (itf? " itf": "") + ')';
    }

Code snippet of <org.springframework.asm.Handle: toString()Ljava/lang/String;> in org.springframework:spring-core:4.2.1.RELEASE (loaded version):

public String toString() {
        return owner + '.' + name + desc + " (" + tag + ')';
    }

Suggested solutions:

Solution: Update direct dependency org.springframework:spring-core from 4.2.1.RELEASE to 4.3.10.RELEASE.

Thanks. Best regards, Coco
