Caliper：如果我使用measureMemory参数运行，则出现ConfigurationException

Question

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

不知道我错过了什么。我在本地构建了卡尺罐。如果没有这个参数，一切都会很好。我想看看我的操作消耗了多少内存

Answer 1

我必须按照 http:// 中提到的方式定义 ALLOCATION_JAR code.google.com/p/caliper/issues/detail?id=114&sort=-id。已在 CentOS-6 和 Mac OSX 10.7.2 中测试过

Answer 2

2 个问题，一个是 Maven 依赖项带来了损坏的 Allocation.jar，另一个是（如其他答案所述）您需要定义 ALLOCATION_JAR 环境变量。尝试并按照此帖子 将其设置为 Ant 构建的一部分，看看是否有帮助。
