Apache Velocity 2.0 脚本编译不工作

Question

我正在尝试检查提供 JSR 223 实现和 support of Compilable

的速度脚本引擎 2.0

the Compilable interface has been implemented in the process.

我使用 jars：velocity-engine-scripting-2.0.jar、velocity-1.7.jar、commons-collections-3.2.2.jar

来自我使用下面的代码

//class org.apache.velocity.script.VelocityScriptEngine
final ScriptEngine engine = engineFactory.getScriptEngine();
        if (engine instanceof Compilable) {
            try {
                ((Compilable) engine).compile("");
 ...

对于速度，我得到以下信息：

javax.script.ScriptException: org.apache.velocity.exception.ResourceNotFoundException: No template name provided
    at org.apache.velocity.script.VelocityScriptEngine.compile(VelocityScriptEngine.java:311)
    at org.apache.velocity.script.VelocityScriptEngine.compile(VelocityScriptEngine.java:288)
    at com.Workers.LevelCheck.main(LevelCheck.java:69)
Caused by: org.apache.velocity.exception.ResourceNotFoundException: No template name provided
    at org.apache.velocity.runtime.resource.loader.StringResourceLoader.getResourceStream(StringResourceLoader.java:353)
    at org.apache.velocity.Template.process(Template.java:108)
    at org.apache.velocity.script.VelocityScriptEngine.compile(VelocityScriptEngine.java:306)
    ... 2 more

此外，当我尝试提供模板名称时 ((Compilable) engine).compile("v.vm"); 它失败并出现相同的异常

您不能将 velocity-engine-scripting-2.0.jar 与 velocity-1.7.jar 一起使用，否则您需要使用 velocity-engine-core-2.0.jar你会得到不可预测的结果。
