java.lang.NoClassDefFoundError 对于 clojure.java.api.Clojure
java.lang.NoClassDefFoundError for clojure.java.api.Clojure
我们正在为一个毫无意义的 java.lang.NoClassDefFoundError 苦苦挣扎。
相同 WAR 文件在服务器 B 中运行完美，但在服务器 A 上抛出 java.lang.NoClassDefFoundError。
配置为：
服务器 A（抛出异常）：
OS:
NAME="SLES"
VERSION="12-SP4"
VERSION_ID="12.4"
PRETTY_NAME="SUSE Linux Enterprise Server 12 SP4"
Apache Tomcat 8.5.49
Oracle Java dk1.8.0_231
服务器 B（完美运行）：
OS:
NAME="Ubuntu"
VERSION="16.04.6 LTS (Xenial Xerus)"
ID=ubuntu
ID_LIKE=debian
VERSION_ID="16.04"
PRETTY_NAME="Ubuntu 16.04.6 LTS"
Apache Tomcat 8.5.37
Oracle Java jdk 1.8.0_201-b09
例外情况是：

WAR 文件在服务器 B 上运行完美，但在服务器 A 上抛出异常。
我们检查了 tomcat 下的 ~/WEB-INF/lib/ 文件夹，必要的依赖项 (clojure-1.9.0.jar) 在那里并且是一致的。孤注一掷，我们甚至尝试过手动更换新的jar文件，但没有成功。
来自 Why am I getting a NoClassDefFoundError in Java? :
java.lang.NoClassDefFoundError This exception indicates that the JVM
looked in its internal class definition data structure for the
definition of a class and did not find it. This is different than
saying that it could not be loaded from the classpath. Usually this
indicates that we previously attempted to load a class from the
classpath, but it failed for some reason
请指教！

看起来 Tomcat 8.5.50 在 Catalina 中包含了一堆回归修复和资源加载，这可能会影响 Clojure 源文件的加载。建议降级到与工作相同的版本或升级到 8.5.50。
