HeidelTime：如何在 jar 中正确打包 HeidelTime？
HeidelTime: How to package HeidelTime correctly within a jar?
我使用 here 中的 HeidelTimeWrapper，向其添加参数 PARAM_TEMPONYMS 并在我的 uimaFit 管道中像这样初始化它：
AnalysisEngineDescription heidelTimeEnglish = createEngineDescription(HeidelTimeWrapper.class,
HeidelTimeWrapper.PARAM_LANGUAGE, "english",
HeidelTimeWrapper.PARAM_TYPE_TO_PROCESS, "narrative",
HeidelTimeWrapper.PARAM_DATE, true, HeidelTimeWrapper.PARAM_DURATION, true,
HeidelTimeWrapper.PARAM_TIME, true, HeidelTimeWrapper.PARAM_SET, true,
HeidelTimeWrapper.PARAM_TEMPONYMS, false, HeidelTimeWrapper.PARAM_GROUP, true);
当 运行 Eclipse 中的应用程序时，此解决方案有效。但是在将应用程序打包到 jar 中时我会遇到错误：

用 HeidelTime 构建 jar 时如何正确打包？
几个小时后，我用 Spring Boot Maven 插件解决了我的问题。
该插件有一个名为 <requiresUnpack> 的参数。将此参数与 heideltime-dependency 添加在一起可以让我打包我的应用程序并 运行 它成功。我也摆脱了 maven-assembly-plugin。
