发现没有可行的替代方案 - Java Maven项目中的Ruta

Question

以下脚本在Ruta工作台中运行正常。然而，当我在触发Ruta脚本的现有Java Maven项目中包含相同内容时，我得到“找不到可行的替代”异常。为什么会这样？如何解决这种异常？

脚本：

    CssDefinition{->onlyClass=false, family = CssDefinition.fontfamily, size = CssDefinition.fontsize, color = CssDefinition.fontcolor}
        <-{CssStyles{PARSE(cssStylesStr),IF(contains(cssStylesStr,tagClass))};};

PS： 我已经遇到过与其他一些脚本相同的场景。

Answer 1

解析异常是由结合项目设置的分析引擎配置引起的。引擎无法初始化扩展包含contains字符串函数：

WARNING: Failed to initialze extension org.apache.uima.ruta.string.StringOperationsExtension

因此，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。假设它是允许的，那么对于下一个(，没有可行的替代方案。

这个问题最有可能通过在类路径中添加ruta-core-ext来解决。
