自Eclipse更新到2018-12之后，我无法使用Query构建任何Acceleo项目。
我使用Acceleo 3.7.7
并将EMF更新为无效版本以解决此问题： https://bugs.eclipse.org/bugs/show_bug.cgi?id=543103
例如我得到这样的错误：
An error has occurred during the loading of 'platform:/resource/myProject/bin/com/xxxx/z/acceleo/module/program/utils/ServiceUtils.emtl'.

我的mtl文件是这样的：
[query public isProgram（arg0：ProgramModel）：布尔值 = invoke（'com.xxxx.z.acceleo.module.program.utils.ServiceUtils'，'isProgram（z.ProgramModel）'，Sequence {arg0}） /]
您有解决我问题的想法吗？ 在Eclipse和Acceleo更新之前，我可以构建项目。 我试过-clean eclipse参数，清理项目，重新安装eclipse，创建没有问题更改的新工作区
