命名Talend自定义组件-除tTutorialRow外不工作

我一直在跟踪Talend tutorial 关于“如何创建自定义组件”。如果我逐字逐句地遵循这个示例,那么我的文件命名如下并放在文件夹中 tTutorialRow ,教程工作:

tTutorialRow_java.xml
tTutorialRow_messages.properties
tTutorialRow_begin.javajet
tTutorialRow_main.javajet
tTutorialRow_end.javajet

这使用以下代码:

t教程行_java.xml:

  <CODEGENERATION/>

  </RETURNS>
  
</COMPONENT>

t自动行消息属性:

LONG_NAME=Tutorial component
HELP=org.talend.help.TutorialRow
 
NB_LINE.NAME=Number of lines
ADDRESSES.ITEM.USERNAME=Username
ADDRESSES.ITEM.DOMAIN=Domain
ADDRESSES.NAME=Addresses

    globalMap.put("<%=cid %>_NB_LINE",nb_line_<%=cid %>);

如果我从以下位置更改文件名:

t教程行_java.xml
t自动行消息属性
t教程Row_begin.javajet
t教程Row_main.javajet
t教程Row_end.javajet

至:

myProject_java.xml
myProject_messages.properties
myProject_begin.javajet
myProject_main.javajet
myProject_end.javajet

并将文件夹名称更新为myProject,添加组件将不再有效。如何使用新名称添加组件?

谢谢
