我正在尝试运行此处（https://github.com/dacapobench/dacapobench）提供的 daCapo 基准测试。

我给了 JAVA_HOME 作为export JAVA_HOME="/home/srcshetty/Desktop/ALL_JDKs/jdk-13.0.1/"

我已经安装了构建基准测试所需的所有依赖项。

ant lusearch我通过在文件夹中运行来测试 lusearch 基准benchmark。

当我使用JDK12及以下版本时它运行成功，而当我使用JDK13时它不起作用。

我收到以下 JDK13 错误消息。

当我使用 JDK12 运行时，我必须将源代码从 1.5 更改为 1.7 或更高版本并成功构建，并且我也成功运行了基准测试。但是使用 JDK13，我得到了上述错误，我无法弄清楚。

Lucene 构建使用编译器 ( -Xdoclint) 的 doclint 特性，看起来它在 JDK 13 中变得更加严格。标志设置在lucene/common-build.xml...中-Djavac.doclint.args=""。
