optaplanner Matrix benchmarking failed 原因：Unmarshalling of benchmarkConfigResource failed on line number (40)

如何解决optaplanner Matrix benchmarking failed 原因：Unmarshalling of benchmarkConfigResource failed on line number (40)

我之前在没有基于模板的基准测试的情况下成功使用了基准测试，但是基于模板的基准测试在这里不能工作。 我使用 https://docs.optaplanner.org/

中的测试用例

<plannerBenchmark>
  <benchmarkDirectory>local/data</benchmarkDirectory>
  <parallelBenchmarkCount>(availableProcessorCount / 2)+1</parallelBenchmarkCount>
  <warmUpSecondsspentLimit>60</warmUpSecondsspentLimit>
  <inheritedSolverBenchmark>
    ...
  </inheritedSolverBenchmark>

<#list [5,7,11,13] as entityTabuSize>
<#list [500,1000,2000] as acceptedCountLimit>
  <solverBenchmark>
    <name>Tabu Search entityTabuSize ${entityTabuSize} acceptedCountLimit ${acceptedCountLimit}</name>
    <solver>
      <localSearch>
        <unionMoveSelector>
          <changeMoveSelector/>
          <swapMoveSelector/>
        </unionMoveSelector>
        <acceptor>
          <entityTabuSize>${entityTabuSize}</entityTabuSize>
        </acceptor>
        <forager>
          <acceptedCountLimit>${acceptedCountLimit}</acceptedCountLimit>
        </forager>
      </localSearch>
    </solver>
  </solverBenchmark>
</#list>
</#list>
</plannerBenchmark>

好像有问题

<#list [5,13] as entityTabuSize>

optaPlanner 版本是 7.43.0 xstream 版本为 1.4.14

有sonme错误信息

解决方法

根据stacktrace，您使用的是PlannerBenchmarkConfig.createFromXmlResource()，可用于读取基准配置XML，但不能读取FreeMarker 模板。 要读取基准配置 FreeMarker 模板，请使用 PlannerBenchmarkConfig.createFromFreemarkerXmlResource() 方法之一。 有关详情，请参阅 Template-based benchmarking。
