Hi,

That is because, on Mac, Eclipse files are combined into Eclipse.app file which Lombok does not natively recognized. So for those who has the same problem, here are the step to do just that. Note that this is tested for Eclipse Oxygen (or Photon) on macOS Sierra (verion 10.12.3). However, if you’re a hardcore programmer, then you really should get your hands dirty with the command line via OS X’s Terminal. This lets you get down to the UNIX core. When you go into your Eclipse install directory, you’ll find a nice executable named appropriately enough: “eclipse”. On Windows 10, Start All Programs Samples Console (enUS). The variable package group refers to the package group specified in IBM® Installation Manager during installation. The default package group is Operational Decision Manager V 8.10.4. This shortcut opens Designer in the enUS (American English) locale. On all platforms, start Rule Designer by using the Eclipse. Upgrade Upgrade to the latest eclipse version There are many performance enhancements done in recent version of eclipse.If you are using an older version you may want to. In Luna, and prior, the Eclipse.app was a sub-directory of the eclipse folder. In Mars this has been inverted. Whatever the reason, lombok won't install on my mac. Vm value: Mac OS X Example On a Mac OS X system, you can find eclipse.ini by right-clicking (or Ctrl+click) on the Eclipse executable in Finder, choose Show Package Contents, and then locate eclipse.ini in the MacOS folder under Contents.

I just updated Eclipse on my MacOS X using Eclipse updating wizard. After updating I get the following: “The eclipse executable launcher was unable to locate its companion shared library“. Here’s what I’ve done to track and fix the issue:

1) Run eclipse from the console and check the output:

dhcp5:~ ppires$ /usr/local/eclipse-ganymede/Eclipse.app/Contents/MacOS/eclipse
dlopen(../../../plugins/org.eclipse.equinox.launcher.carbon.macosx_1.0.100.v20080509-1800, 2): image not found

2) Check if plugins/org.eclipse.equinox.launcher.carbon.macosx_1.0.100.v20080509-1800 exists:

dhcp5:eclipse-ganymede ppires$ ls plugins/org.eclipse.equinox.launcher.carbon*
org.eclipse.equinox.launcher.carbon.macosx_1.0.101.R34x_v20080731/

3) See the difference? OK, so now let’s fix it! Edit your Eclipse.app/Contents/MacOS/eclipse.ini and make the necessary changes.

4) Run it and be happy!

I’m trully disappointed that this kind of issues still happen on this so amazing product that so many people are using nowadays. Not everyone has the experience to trial and solve these errors, and that’s very negative for Eclipse, as developers will look somewhere else, like Netbeans or others.

• 2Specifying the JVM
  • 2.3-vm value: macOS Example

Eclipse startup is controlled by the options in $ECLIPSE_HOME/eclipse.ini. If $ECLIPSE_HOME is not defined, the default eclipse.ini in your Eclipse installation directory (or in the case of Mac, the Eclipse.app/Contents/MacOS directory) is used.

eclipse.ini is a text file containing command-line options that are added to the command line used when Eclipse is started up. There are many options available, please see here.

Important:

1. You can, and should, experiment with changes to the launch command from your Command Prompt/Terminal before changing the eclipse.ini itself.
2. Each option and each argument to an option must be on its own line.
3. All lines after -vmargs are passed as arguments to the JVM, so all arguments and options for eclipse must be specified before -vmargs (just like when you use arguments on the command-line)
4. Any use of -vmargs on the command-line replaces all -vmargs settings in the .ini file unless --launcher.appendVmargs is specified either in the .ini file or on the command-line. (doc)
5. -XX VM arguments are subject to change without notice, even during minor updates. If the JVM keeps exiting with code 2 instead of starting Eclipse, try removing them.
6. Make a backup--keep a copy of the original contents on hand so you don't break your installation and have to download it all again.

By default, eclipse.ini looks something like this (the exact contents will vary based on operating system and which Eclipse package you have):

Among other things, this sets the heap space to 40MB initially and a maximum of 512MB, and also specifies a maximum PermGen size of 256MB. A max heap of 512MB might be OK for some users, but it's often necessary to bump that value up for large project sets or when some third-party plugins are installed.

One of the most recommended options to use is to specify a specific JVM for Eclipse to run on. Doing this ensures that you are absolutely certain which JVM Eclipse will run in and insulates you from system changes that can alter the 'default' JVM for your system. Many a user has been tripped up because they thought they knew what JVM would be used by default, but they thought wrong. eclipse.ini lets you be CERTAIN.

The following examples of eclipse.ini demonstrate correct usage of the -vm option.

Note the format of the -vm option - it is important to be exact:

• The -vm option and its value (the path) must be on separate lines.
• The value must be the full absolute or relative path to the Java executable, not just to the Java home directory.
• The -vm option must occur after the other Eclipse-specific options (such as -product, --launcher.*, etc), but before the -vmargs option, since everything after -vmargs is passed directly to the JVM.
• For the 32-bit Eclipse executable (eclipse.exe on Windows) a 32-bit JVM must be used and for the 64-bit Eclipse executable a 64-bit JVM must be used. 32-bit Eclipse will not work with a 64-bit JVM.

Here is an example of what eclipse.inimight look like on a Windows system after you've added the -vm argument and increased the maximum heap space:

Remember that the exact values will differ slightly depending on operating system and Eclipse package.

-vm value: Windows Example

This is how the -vm argument might look on Windows (your exact path to javaw.exe could be different, of course. Please beware of paths that contain a space, the examples below do not have any spaces, and using quotation marks around paths that contain spaces does not seem to work):

Or

An alternative way is to insert the following VM option before the -vmargs option in the Eclipse shortcut's properties (edit the field Target inside the 'Shortcut' tab):

or

This might not work on all systems. If you encounter 'Java was started but returned exit code=1' error while starting the eclipse, modify the -vm argument to point to jvm.dll (exact path could be different):

-vm value: Linux Example

This is how the -vm argument might look on Linux (your exact path to java could be different, of course):

-vm value: macOS Example

On a macOS system, you can find eclipse.ini by right-clicking (or Ctrl+click) on the Eclipse executable in Finder, choose Show Package Contents, and then locate eclipse.ini in the Eclipse folder under Contents. The path is often:/Applications/Eclipse.app/Contents/Eclipse/eclipse.ini

For versions of Mac OS X 10.7+ is something like:

For example, the latest JDK 1.8 (as of July 2015) is/Library/Java/JavaVirtualMachines/jdk1.8.0_51.jdk/Contents/Home/bin

For standard Mac Java installations and so you don't have to continually update the setting when you install new Java VMs, set the -vm flag to simply /usr/bin:

If you want to use another JDK (that has the macOS directory layout, like the .tar.gz from AdoptOpenJDK) you should use:

For JDKs without macOS directory layout see: Using a JDK without macOS directory layout

Essential Macos Apps

NOTE: Occasionally, depending on the version of your macOS and whether or not you had already run this particular Eclipse installation before, upon launch after changing the -vm, you may run into an error that says 'the application is damaged and can't be opened'. This is the expected behavior since you just modified a signed/notarized app. This problem can be overcome by opening the Eclipse application once before changing the eclipse.ini file. Alternatively, running of the following command can fix the issue too: xattr -cr Eclipse.app

Here is additional information:

Perhaps the best way to determine the location for the JDK you want to use is with the utility

From the list produced by that command, select the JDK you want to use and put that path into the eclipse.ini file, making sure to append /bin/java to the path (eg, /Library/Java/JavaVirtualMachines/jdk1.8.0_51.jdk/Contents/Home/bin/java

Note that the full path can either include java or not. For example, the following will both work:

Using a JDK without macOS directory layout

If you want to use a JDK that doesn't follow the macOS directory layout, like the ones installed through SDKMAN!, then you need to specify the path to the libjli.dylib file.

For JDK 11+: <JDK_11+_HOME>/lib/jli/libjli.dylib

For JDK 8: <JDK_8_HOME>/jre/lib/jli/libjli.dylib

Examples using SDKMAN!

NOTE: Beware that if you use current instead of using a specific JDK version identifier it will use the default if you launch the Eclipse.app using the UI (double-click or using Spotlight). If you launch it from a terminal it will use the one currently selected.
