我希望通过复制Java文件夹的内容并设置环境变量来确保一切都能正常工作。
我通常在虚拟机中运行安装程序，压缩\java文件夹内容，回到虚拟机的快照，然后解压缩压缩文件。
我找不到一个地方有最新的JRE / JDK压缩文件…
http://java.sun.com/javase/downloads/index.jsp
http://download.java.net/jdk6/
另外，假定sun的exe安装程序只是解压缩整个文件，而不会弄乱注册表、环境变量等等，这是否安全?

用jdk-8u74-macosx-x64.dmg测试。
从Oracle下载。dmg 挂载磁盘映像 提取.pkg，拖动它。不要双击(它会安装)。 打开一个终端并cd到包中。 Mkdir jdk-$version && CD jdk-$version xar -xf ../JDK*.pkg cd jdkTAB tar zxf有效负载 “Contents/Home”文件夹中包含JDK
不幸的是，JDK不能作为可移植的ZIP文件提供。但是，你可以遵循以下步骤:
Create working JDK directory (C:\JDK in this case) Download latest version of JDK from Oracle (for example jdk-7u7-windows-x64.exe) Download and install 7-Zip (or download 7-Zip portable version if you are not administrator) With 7-Zip extract all the files from jdk-XuXX-windows-x64.exe into the directory C:\JDK Execute the following commands in cmd.exe: cd C:\JDK\.rsrc\1033\JAVA_CAB10 extrac32 111 Unpack C:\JDK\.rsrc\1033\JAVA_CAB10\tools.zip with 7-zip Execute the following commands in cmd.exe: cd C:\JDK\.rsrc\1033\JAVA_CAB10\tools\ for /r %x in (*.pack) do .\bin\unpack200 -r "%x" "%~dx%~px%~nx.jar" (this will convert all .pack files into .jar files) Copy all contents of C:\JDK\.rsrc\1033\JAVA_CAB10\tools where you want your JDK to be Setup JAVA_HOME and PATH manually to point to your JDK dir and its BIN subdirectory.
Sun JVM可以作为MSI，它可以从脚本执行。

我用exe安装程序安装了JDK 8，然后卸载了JRE，我现在有JDK文件夹，没有env变量或其他设置更改。
The Process described by Igor and CharlesB Works to me, since IDE's like NetBeans and Eclipse permit specify the location of the JDK, even software like Apache Tomcat (the ZIP Distribution) use BASH - FILES to set it up (then specify the JDK location using relatives URI). I Have a USB-HardDisk With NetBeans, Eclipse, Apache Tomcat working with a JDK in "portable mode". I Had a way to extract a copy of the JDK from the installers files: Install it, Copy it in other place and then uninstall it. A dirty way to extract it, but was successfull. The place to put EXTRA - LIBS was: %PLACE_WHERE_JDK_ARE%\jre\lib\ext
