Dependency conflict issue: Exception in thread "main" java.lang.NoSuchMethodError, caused by multiple versions of com.google.guava:guava:jar

[LeoAugust19]

Hi, @izrik there are multiple versions of com.google.guava:guava:jar in com.rackspacecloud:blueflood-core:jar:2.0.0-SNAPSHOT. As shown in the following dependency tree, only the newer version 19.0 will be loaded and the other versions will be shadowed, according to "Maven's nearest wins strategy", during the packaging process.

However, method <com.google.common.io.Closeables: void closeQuietly(java.io.Closeable)> is removed from > guava 16.x, therefore it can not be loaded via guava 19.0. As a result, when your project referencing the missing method, an exception will be thrown.

Solution

Upgrade org.apache.curator:curator-framework:jar:2.3.0:compile and org.apache.curator:curator-recipes:jar:2.3.0:compile to 2.7.1.

Thanks. Regards, Leo
