Pentaho - 使用 XUL 定义时出错

Question

我在运行 Catalina 的 Mac 上遇到了 Pentaho Community Edition 的问题。当我去创建一个新的数据库连接或编辑一个现有的连接时，我收到一条错误消息，说Error working with XUL definition和org.pentaho.ui.xul.XulException: java.lang.reflect.InvocationTargetException。

错误详情如下：

我正在运行 Java 8，并且已将 swt.jar 文件替换为最新版本。知道我可以采取哪些其他步骤来缓解这个问题吗？

Answer 1

我遇到了同样的问题，结果发现这是最新版本的 Java 8 (u291) 的问题。我降级到jdk-8u202并使用pdi-ce-9.1.0.0-324附带的默认swt.jar文件。

卸载当前版本的 Java：

在终端窗口中复制并粘贴以下命令：

    sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
    sudo rm -fr /Library/PreferencePanes/JavaControlPanel.prefPane
    sudo rm -fr ~/Library/Application\ Support/Oracle/Java

下载并安装旧版本：

不要忘记交换 /Applications/data-integration/libswt/osx64 中的 swt.jar 文件

您可能需要重新下载原始数据集成文件夹才能获取正确的 swt.jar 文件（这就是我所做的）。
