在我们的项目（Eclipse插件）中，我们尝试以编程方式安装几个插件（不用担心，用户首先必须接受所有许可证）。一切正常，插件安装完毕，除了某个错误不断弹出：

我们已经尝试了一些方法，比如在pom.xml中设置我们不想使用镜像的tycho，或者将它作为JVM参数设置，或者只是将System属性设置为不使用镜像。但是，据我所知，这只会取消noneclipse.org网站，这是一个eclipse.org网站......
要安装的更新内容是：http://download.eclipse.org/modeling/emf/teneo/updates/2.0.0/interim/（适用于Teneo）。
如何防止此错误发生？要明确：这不会阻止代码按预期运行。 Teneo安装完毕。我只是不希望在错误日志中弹出这种错误。
感谢您的任何提示。
