下面的脚本在Ruta工作台中运行良好。而当我在触发Ruta脚本的现有Java Maven项目中包含相同代码时，会出现“找不到可行的替代方法”异常。为什么会发生？如何解决此类异常？
脚本：
CssDefinition{->onlyClass=false, family = CssDefinition.fontfamily, size = CssDefinition.fontsize, color = CssDefinition.fontcolor}
<-{CssStyles{PARSE(cssStylesStr),IF(contains(cssStylesStr,tagClass))};};

PS：
我已经在其他脚本中遇到过相同的情况。
最佳答案
解析异常是由分析引擎的配置与项目设置的组合引起的。引擎未能初始化包含contains字符串函数的扩展名：
WARNING: Failed to initialze extension org.apache.uima.ruta.string.StringOperationsExtension
结果，解析器无法将部分
IF(contains(cssStylesStr,tagClass))标识为正确的条件，因为contains不是布尔变量或其他允许的构造。假设允许这样做，那么对于下一个(，没有可行的选择。通过将ruta-core-ext添加到类路径中，很可能可以解决此问题。
