使用下载页面中的简单步骤无法在 Windows 10 上运行Blazegraph（Java RDF 三重存储） 。
我有一台安装了 Java JDK 9 的 Windows 10 机器（请参阅下面的版本检查）。我下载了最新的 Blazegraph 可执行 jar，然后运行“java -server -Xmx4g -jar blazegraph.jar”。它报告 NullPointerException，如下所示。如果有帮助，下面的错误引用StandaloneNanoSparqlServer.java:142，github显示为"System.setProperty("jetty.home", jettyXml.getClass().getResource("/war").toExternalForm());".
