How do I run Eclipse using Oracle's new 1.7 JDK for the Mac?

Question

I\'m trying to get the new 1.7 JDK working with Eclipse (this is Oracle\'s official release).

I don\'t mean just pointing Eclipse to it so you can use it in projects

Answer 1

As of 2012-04-28, it is a known unresolved bug in Eclipse 3.7 SR2 launcher app.

See https://bugs.eclipse.org/bugs/show_bug.cgi?id=339788

Answer 2

By default, your MacOSX comes with JRE 1.6.0 which is not suitable for Eclipse. To resolve issue you also need to install JDK 7 which already includes JRE 1.7.0.

Here is link that you can download.

Just select MacOS X version under Java SE Development Kit 7u79 and install it.

After installation this package, Eclipse will start without any more modification.

Apparently there is a fix for Kepler that should come out in the next service release.

Meanwhile, there is a workaround that is mentioned in this bug that will allow you to run eclipse without ever installing JRE 1.6 from Apple: https://bugs.eclipse.org/bugs/show_bug.cgi?id=411361#c20

This will allow you to launch eclipse from the finder or spotlight but not the dock.

I've just tested this on OS X Mavericks, which during the update loses jre 6 and asks for it to be installed when you try to launch Eclipse. I have the latest Oracle JDK 1.7 installed of course.

Decline to do that and then to work around this, edit the jvm capabilities in /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Info.plist

<key>JVMCapabilities</key>
            <array>
                    <string>CommandLine</string>
                    <string>JNI</string>
                    <string>BundledApp</string>
                    <string>WebStart</string>
                    <string>Applets</string> 
            </array>

With this fix, you don't need to specify the vm in eclipse.ini.

Answer 4

Check your java_home is corrento in /usr/libexec/java_home;

Do not change your eclipse.ini and edit the Info.plist file and change/add this line < string>-vm< /string>< string>/Library/Java/JavaVirtualMachines/'jdk-version-your'/Contents/Home/bin/java< /string> and save. Open Eclipse and done!

For me it worked well, and to use javafx e(fx)clipse!

PS: On a Mac OS X system, you can find Info.plist by right-clicking (or Ctrl+click) on the Eclipse executable in Finder, choose Show Package Contents, and then locate Info.plist in the Contents folder.

I just added my comment to https://bugs.eclipse.org/bugs/show_bug.cgi?id=339788 regarding the inability to use the new Oracle JDK with Eclipse on OS X. Using the -vm option inside eclipse.ini does not work. The only way I found to work around this was to use the following shell script:

#!/bin/sh
#
export JAVA_HOME=/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home
LAUNCHER_JAR=/Applications/eclipse/plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar

java \
-showversion \
-XX:MaxPermSize=256m \
-Xms1024m \
-Xmx1024m \
-Xdock:icon=/Applications/eclipse/Eclipse.app/Contents/Resources/Eclipse.icns \
-XstartOnFirstThread \
-Dorg.eclipse.swt.internal.carbon.smallFonts \
-Dosgi.requiredJavaVersion=1.5 \
-jar $LAUNCHER_JAR

Using the steps on http://mathiasbynens.be/notes/shell-script-mac-apps, I turned the script above into an application that I can keep on my dock.

There is another way. Please add two following lines before -vmargs in the .ini file:

-vm 
{YOUR_JAVA_7_HOME}/jre/lib/server/libjvm.dylib

(remember these need to be separate lines) and also add a corresponding entry in 'Info.plist' file (add or modify array items under "Eclipse" key - each string child element corresponds to a command line parameter).

...
<key>Eclipse</key>
<array>
<string>-vm</string>
<string>/{MY_VM_HOME}/jre/lib/server/libjvm.dylib</string>
...
</array>

Alternatively just use -vm {YOUR_JAVA_7_HOME}/lib/server/libjvm.dylib command line parameter when running eclipse from terminal.
