新人求助：安装java反编译工具JD后无法使用

[snowly15]

如题：上使用eclipse安装java反编译工具enhanced java compiler，安装成功后重启，发现在系统设置里java下面没有反编译的配置，同时反编译也不好用。eclipse上check update时，也报错了
--------------------
系统：macos系统10.15.6 (19G73)
eclipse版本：Version: 2020-06 (4.16.0)
jd的jar包：org.jd.ide.eclipse.feature_2.0.0.jar（jd-eclipse-2）
------------------------------------------------------------------------------
jd安装信息在已经安装的应用上可见：

软件更新时报错信息如下：

顶一个，macOS最新系统使用eclipse market里的enhanced java compiler 反编译的确安装不上。下载到本地也没用。

换idea啊 自带反编译

[windlysnowly]

我的是macOS，jad是装上了，就是Preference里面没有出现jad的配置

[qq_39936465]

反编译工具是用来打开class文件的吧，ide不需要设置，安装完可以直接打开class文件，class文件已经被反编译成java文件

javadoc 那个反编译
