java.lang.NoSuchMethodError caused by dependency conflicts of multiple versions of logback #272

Open LeoAugust19 opened 6 years ago

LeoAugust19 commented 6 years ago

Hi, there are multiple versions of ch.qos.logback:logback-classic:jar in org.mayocat.platform:mayocat-platform-model:jar:0.30.1. Due to Maven version management, only ch.qos.logback:logback-core:jar:1.0.10 can be loaded and the other versions will be shadowed during the packaging process.

However, method <ch.qos.logback.core.util.Loader: java.util.Set getResourceOccurenceCount(java.lang.String,java.lang.ClassLoader)> only defined in the shadowed version ch.qos.logback:logback-core:jar:1.0.6. As a result, an exception will be thrown when your project referencing the missing method.

Dependency tree org.mayocat.platform:mayocat-platform-model:jar:0.30.1 +- org.xwiki.commons:xwiki-commons-observation-api:jar:4.5.2:compile +- com.yammer.dropwizard:dropwizard-core:jar:0.6.2:compile | +- com.yammer.metrics:metrics-logback:jar:2.2.0:compile | +- ch.qos.logback:logback-core:jar:1.0.10:compile | +- (ch.qos.logback:logback-classic:jar:1.0.10:compile - omitted for conflict with 1.0.6) | - com.fasterxml.jackson.datatype:jackson-datatype-joda:jar:2.1.2:compile | +- (com.fasterxml.jackson.core:jackson-core:jar:2.1.2:compile - omitted for conflict with 2.1.4) | +- (com.fasterxml.jackson.core:jackson-databind:jar:2.1.2:compile - omitted for conflict with 2.1.4) | - (joda-time:joda-time:jar:2.1:compile - omitted for conflict with 2.2) +- ch.qos.logback:logback-classic:jar:1.0.6:compile | +- (ch.qos.logback:logback-core:jar:1.0.6:compile - omitted for conflict with 1.0.10) | - (org.slf4j:slf4j-api:jar:1.6.5:compile - omitted for conflict with 1.7.4) - org.jmock:jmock:jar:2.6.0-RC2:compile +- org.hamcrest:hamcrest-core:jar:1.3.RC2:compile - org.hamcrest:hamcrest-library:jar:1.3.RC2:compile - (org.hamcrest:hamcrest-core:jar:1.3.RC2:compile - omitted for duplicate)

Solution Upgrade ch.qos.logback:logback-classic to version 1.0.10.

Do you need stack trace or test case to investigate this issue? I can try to provide you more information.

Thanks a lot.

Regards, Leo

@jvelo Hi, may I pull a request to fix this issue?

jvelo commented 6 years ago

@LeoAugust19 yes, of course. I'm not active on the project any longer but will merge good pull requests. FYI I'm open to grant commit rights if there are parties interested in moving the project forward.
