Question

当我打开measureMemory参数时，我收到ConfigurationException（代理库失败）在Caliper来源的Tutorial.java中（http://code.google.com/p/caliper/source/browse/#svn%2Ftrunk%2Ftutorial）

不确定我错过了什么。我在当地建造了卡尺罐。没有这个参数，一切都很好。我想看看我的操作消耗的内存

Answer 1

我必须按照http://code.google.com/p/caliper/issues/detail?id=114&sort=-id中的提法定义ALLOCATION_JAR。已经在CentOS-6和Mac OSX 10.7.2中进行了测试

Answer 2

2个问题，一个是maven依赖带来一个破坏的allocation.jar，另一个是（正如其他答案所提到的）你需要定义ALLOCATION_JAR环境变量。尝试并按照此post将其设置为Ant构建的一部分，看看它是否有帮助。
