This teaches a new lesson: Always build from command prompt! I tried it using command prompt and the build was successful.

Then I tried /d/thrift demo/ and there is the problem. I tried placing the thrift executable at /d/thrift/ and it worked and assigning THRIFT_HOME = /d/thrift. That's a big problem when working on Windows.

So there you have it, as with prior versions of Java, if you have multiple installed you still have to setup and add JAVA_HOME to your Windows PATH variable, but starting with Java 8 you now must be particular about adding the JAVA_HOME entry at the front of the path.I am currently using on Windows 7 and the problem was with spaces in the folder name.
So rather than chase down all the possible directories that the installer put Java, and to avoid deleting the System32 files that actually may be necessary to some process somewhere, I decided that simply prepending my preferred Java Home directory to the path was best option.
Yes, I thought of that too, but the installer also copies the java.exe, javaw.exe, and javaws.exe files to C:\Windows\System32 directory, which is also in the Windows PATH variable. You might suggest to simply remove the Oracle Java path that was prepended to your Windows PATH by the installer. Why not just remove the Oracle Java path entry and not worry about your JAVA_HOME placement in the Path? If I suffixed it to the end of the Windows PATH variable then Java 8 was always being picked up (Windows searches the directories left-to-right in the PATH variable). Since the installer prepended the Oracle Java path to the front of the Windows PATH variable, I needed to create my own custom JAVA_HOME environment variable pointing to the directory of Java 7 then prepend %JAVA_HOME%\bin to my Windows PATH variable so that it was the first search directory.
Want to change Java Version/JAVAHOME for Ant builds Open /.antrc file by running vim /.antrc Add JAVACMDSet JAVA_HOME as first entry to Path Variable I wrote this earlier on a Github gist, but putting it here for a consolidated reference.

However, to support multiple versions you must update your Windows PATH. For example, versions 7 and 8, both the 32-bit and 64-bit editions.

If you’re like me, you have different tools that have specific Java version requirements so you install multiple versions of Java. You can readily use the commands java or javac from the command prompt. I noticed starting with version 8 that the Java installer now prepends to the Windows PATH variable C:\ProgramData\Oracle\Java\javapath.įor most casual users and developers that will only have Java 8 installed and not other versions then this should be fine.
