在我的 STS/Eclipse 上对我的代码库 Jasper Studio 插件进行大量更新后停止工作。主要问题是我无法再打开 jrxml 文件了。如果我尝试这样做，我的 STS 中只会打开一个空白的空白页面，在我的代码更新之前，我能够看到完整的 jrxml 布局编辑器。
经过很长时间的调查，我能够让 jrxml 编辑器再次工作，但以相当费力的方式。在我将 pom.xml 回滚到主要代码库更新之前的版本后，编辑器再次开始工作。当然，我的应用程序不会以旧的 pom.xml 开头，但至少我可以将 jasper studio 编辑器与旧的 pom.xml 一起使用。由于许多副作用，在这些 pom.xml 文件之间切换非常耗时，我很想找到更好的解决方案。
以下是在我的主要代码更新期间更新的那些依赖项的列表：
-spring framework 4.1.6. -->4.2.5.
-spring security version 3.2.4 -->4.0.4.
-waffle version 1.6 --> 1.8.1
-jackson version 2.6.3--> 2.7.3.
我的 Jasper studion 插件版本是 6.2.1。
下面是打印到 eclipse/STS 日志的错误消息：
