gradle - java.lang.NoClassDefFoundError:javaslang/collection/LinkedHashMap，同时使用jmh对基准 Spring 数据应用程序进行基准测试

Question

我有spring data JPA应用程序，我想使用jmh对应用程序进行基准测试。

我正在使用gradle构建工具，并为此使用gradle-jmh-plugin。

我的github仓库是here。

我想对要进行基准测试的create Person实体进行基准测试，并且基准测试代码为here。

每当我使用gradle :aerospike-benchmark-demo:jmh --stacktrace命令运行此基准测试时，总是会遇到以下异常。

10:01:40.688 [com.aerospike.benchmark.AerospikeCreateBenchMarkDemo.createPerson-jmh-worker-1] DEBUG org.springframework.beans.factory.support.DefaultListableBeanFactory - Retrieved dependent beans for bean 'aerospikeClient': [aerospikeTemplate]

我不确定如何将AerospikeConfig和PersonRepository自动连接到Benchmarking类。

Answer 1

似乎您缺乏javaslang依赖性。用
compile group: 'com.javaslang', name: 'javaslang', version: '2.0.0-RC4'
添加到aerospike-demo / build.gradle，它运行并至少显示一些数字。
