我的总体目标是编写一个 Storm Topology(版本 0.9.4)。我正在使用 Maven Shade 版本 2.4.3 生成 uber JAR，但尽管我付出了努力，但我仍然得到
java.lang.IllegalStateException: Detected both log4j-over-slf4j.jar AND slf4j-log4j12.jar on the class path, preempting StackOverflowError
当我运行拓扑时。
经过一番阅读后，我排除了 org.slf4j:slf4j-log4j12从 POM (它包含在几个嵌套依赖项中)并运行
mvn dependency:tree
确保slf4j-log4j12不在树上。
但是，当我运行 Maven Shade 时，构建 JAR，执行:
jar -tvf target\StormTopology.jar | grep slf4j
我仍然可以看到 slf4j-log4j12 中的类(class):
0 Wed Jan 20 15:39:48 EST 2016 META-INF/maven/org.slf4j/slf4j-log4j12/
113 Wed Jan 20 15:39:48 EST 2016 META-INF/maven/org.slf4j/slf4j-log4j12/pom.properties

1962 Wed Jan 20 15:39:48 EST 2016 org/slf4j/impl/StaticLoggerBinder.class
1221 Wed Jan 20 15:39:48 EST 2016 org/slf4j/impl/StaticMDCBinder.class
1376 Wed Jan 20 15:39:48 EST 2016 org/slf4j/impl/StaticMarkerBinder.class
我试图排除 slf4j-log4j12来自 Artifact :
<artifactSet>
<excludes>
<exclude>org.slf4j:slf4j-log4j12:*</exclude>
</excludes>
</artifactSet>
我还尝试过过滤slf4j-log4j12 :
<filters>
<filter>
<artifact>*:*</artifact>
<excludes>
<exclude>org.slf4j:slf4j-log4j12:*</exclude>
</excludes>
</filter>
</filter>
我想我不明白 Maven Shade 正在执行的一些基本功能，因为我不明白为什么 slf4j-log4j12一直包含在我的 uber JAR 中。

最佳答案
不幸的是，我的问题以一种超出我控制范围的方式解决了。更新了依赖 JAR 文件之一，删除了对 slf4j-log4j12 的引用。这意味着它不需要被排除在 Storm Topology 项目之外。进行此更新后，问题就消失了。
因此，要么这是一个暂时性问题，要么某处存在一个错误，我无法再花时间进行故障排除。
关于java - Maven Shade 包含 slf4j-log4j12，尽管已明确从 POM 中排除，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34912133/
