Question

我正在尝试使用ycsb tool.i安装java和maven测试mongodb我从https://github.com/brianfrankcooper/YCSB下载了ycsb-master我运行mvn clean package命令以便mongodb绑定成功。加载我执行的工作负载以下命令

C：\ YCSB-master \ bin＆gt; c：\ Python27 \ python.exe ycsb load mongodb -s -P workloads \ workloada -p recordcount = 1000 -threads 6 -p mongodb.url =＆＃34; mongodb： //本地主机：27017＆＃34; -p mongodb.database = test -p writeConcern = normal -p mongodb.auth =＆＃34; true＆＃34;

但我得到的错误就像

[WARN]  Running against a source checkout. In order to get our runtime dependencies we'll have to invoke Maven. Depending on the state of your system, this may take ~30-45 seconds    
[DEBUG]  Running 'mvn -pl com.yahoo.ycsb:mongodb-binding -am package -DskipTests dependency:build-classpath -DincludeScope=compile -Dmdep.outputFilterFile=true'   
Traceback (most recent call last):

    maven_says = get_classpath_from_maven(project)
  File "ycsb", line 178, in get_classpath_from_maven+ err.output)
