将Guava升级到最新的23.5获取用于Preconditions.checkArgument的NoSuchMethodError

Question

在将Guava从18.0升级到最新的23.5-jre时，我遇到了如下异常

Exception in thread "main" java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkArgument(ZLjava/lang/String;Ljava/lang/Object;)V
    at com.van.common.VanExecutors.getSpec(VanExecutors.java:91)
    at com.van.common.VanExecutors.newFixedSizeExecutor(VanExecutors.java:114)
    at com.van.storage.config.ConfigStoreFactory.getOrCreateUncachedStore(ConfigStoreFactory.java:56)
    at com.van.storage.config.ConfigStoreFactory.getOrCreateStore(ConfigStoreFactory.java:74)
    at com.van.storage.config.PolicyManager.loadFromSystemProperties(PolicyManager.java:79)
    at com.van.tools.metric.HbaseMetricStoreSetup.main(HbaseMetricStoreSetup.java:25)

相关代码

private ExecutorSpec getSpec(String executorName) {
        Preconditions.checkArgument(isValid(), "Not initialized");
        Preconditions.checkArgument(NullOrEmpty.isFalse(executorName), "No executor name given");
        Preconditions.checkArgument(POOL_NAME_PATTERN.matcher(executorName).matches(), "Executor name %s must end with -exec", executorName);
        for (ExecutorSpec spec : executorsSpec.getExecutorSpecList()) {
            if (spec.getName().equalsIgnoreCase(executorName)) return spec;
        }
        return null;
    }

根据堆栈跟踪线91是最后的前提检查。

有没有人能告诉我出了什么问题？

Answer 1

为了解决这个问题，我在前面加上了CLASSPATH ( export CLASSPATH=<guava-23.5>;$CLASSPATH )和Guava23.5 jre。

Answer 2

在我看来，方法isValid()返回一个String (这是不是改变了？)而是一个boolean is expected (并且是在release 18 too。
