我有两个名为生成器和执行者的项目（两个maven项目）。我使用apache velocity template engine生成（在 Generator 中）并生成代码，在 Executor 中执行。我希望代码从 Executor 项目运行。我已将 Generator 添加为依赖项，并且能够通过指定执行时所需的模板文件的绝对路径来成功运行。
我想将模板路径设置为相对于类路径并执行maven命令。我在stackoverflow查询中尝试了一切，但我想我肯定错过了成功运行 maven clean install 的东西。
VelocityEngine Velocity = new VelocityEngine();
Velocity.setProperty(RuntimeConstants.RESOURCE_LOADER, "classpath");
Velocity.setProperty("classpath.resource.loader.class",ClasspathResourceLoader.class.getName());
Velocity.setProperty("classpath.resource.loader.path",templatepath);
以上是设置我的Velocity Engine的片段。
templatepath = Templates\\ -> Set relative to classpath ( src/main/resources )
我将模板设为
Template body = Velocity.getTemplate(xmlparsepath);
其中xmlparsepath = XMLParse.vm
预期的程序流程：我需要从Executor项目运行** mvn clean exec：java test **，它应该执行Generator项目（在执行程序中生成junit测试用例）并在Executor项目中运行测试用例。
我得到ResourceNotFoundExceptions，说我无法指向模板文件。但速度记录说不然。 Generator项目中的Velocity日志如下所示。

提前全部谢谢。
答案 0 :(得分：0)
我能够解决它们。我没有使用VM_global_library.vm。我们需要将模板加载到此字段中，如下所示
prop.setProperty("velocimacro.library", "RootTemplate.vm" );
运行时引擎能够以这种方式获取模板。
