错误 NumberFormatException：输入字符串：“2.0”启动 Jdeveloper

Question

我有一个新的 VM，带有从 Oracle 网站下载的 Oracle 12c 12.2.1.1，在测试 Admin 和 SOA 服务器后，我安装了 BPM 并关闭了 VM。

现在，当我尝试启动 Jdeveloper 时出现此错误：

我在网上搜索并找到这个 link 所以我跟踪并删除了 <HOME>/.jdeveloper/system12.1.3.0.41.140521.1008/system_cache 文件夹以及 12.2.1 和 12.2.1.1 的文件夹但没有成功。有什么想法吗？

提前致谢！！

Answer 1

我在使用 OTN 的预构建 VM 时遇到了同样的问题。

我先清除了所有 <HOME>/.jdeveloper/system12.*/system_cache 个文件夹：没有效果。完全删除所有现有 <HOME>/.jdeveloper/system12.* 文件夹：也没有效果。我还删除了所有 <HOME>/.jdeveloper/12.* 文件夹并重新启动了 JDeveloper。仍然是同样的错误。

但现在创建了一个文件夹：<HOME>/.jdeveloper/12.2.1.1.0 和一个 product.conf 文件。

在此文件中，SetJavaHome 被注释掉了。似乎默认 JDK 是问题的根源。我把它改成了SetJavaHome /usr/java/jdk1.8.0_51。保存文件并重新启动 JDeveloper，现在它按预期启动了。

Answer 2

我昨天遇到了类似的问题。以下步骤解决了我的问题。

感谢 Henk Jan 早些时候提供的步骤并帮助我解决了问题。

在/.jdeveloper/.[=10=下清除system*folder/directory后没有解决问题]

我清除了整个 /.jdeveloper/ 目录。

我没有更改 product.conf 文件中的 SetJavaHome 来自 /.jdeveloper/12.2.1.3/

重新启动 JDeveloper 并按预期启动。
