The format of Mac OS X applications has changed in Eclipse Mars to make Eclipse and Eclipse-based applications look more like native OS X applications. This format change was done in a way that is not backwards compatible, however SDC can work around this issue and will not put your users into a broken state.
What does this mean for you? It means if you want to upgrade your existing package to Eclipse 4.5.0 on OS X, you have to run a two stage upgrade flow or run the package’s installer. Because the old provisioning software doesn’t know how to interpret the new format, a single stage upgrade will not be offered to users.

2. See Full List On Eclipse.org

Your options for addressing this issue are as follows:

Option	Steps	Effects
Delayed Update	Revert your changes to the package. Promote the package without changes to take updates to the SDC in-product software updates plugin. Give your users enough time to take the update. You can enable mandatory updates on your package’s security policy to help force adoption. Change the version of the base software to the new version you desire and promote again.	Users who take the first update will see updates as normal going forward. Users who miss the first update or install snapshot versions of this package from before the SDC update will no longer receive in-product updates.
Use a New Package	Create a new package (or clone an existing one) Update that package to the new version of your base software Leave this package on the current version of its base software.	All users who need the new version must switch to the new package. You can help your users migrate to the new package with a notification.
Disable Mac OSX Support for the Package	Turn off Mac OSX support for the package in your its access policy. Promote the access policy Promote the package.	Existing Mac users, if any, will no longer get in-product updates. Windows and Linux users are able to continue using this package without interruption.
Immediate Update	Continue with your promote.	Mac OSX installations will no-longer get in-product updates and users will have to run the new installer.

• Eclipse CDT is supposed to detect where to look for PATH variables and I can't figure out where I would change it or how to change it. Any help would be greatly appreciated! Edit: The original problem was fixed. My PATH variable in eclipse was empty for some reason so I.

• Download the Eclipse Installer. Eclipse is hosted on many mirrors around the world.
• Jun 23, 2020 There is an MQ Explorer plug in for Eclipse. Although using the MQ Explorer is not officially supported on a Mac, but it worked for us on MacOS Mojave 10.14.4, Eclipse 4.7.3a and MQ Explorer 9.1. Download Eclipse 4.7.3a for MacOS from the Eclipse SDK section on the eclipse archive or directly from eclipse-SDK-4.7.3a-macosx-cocoa-x8664.dmg.

Sep 01, 2011 Installing Eclipse. Here’s a handy reference on where to get Eclipse for the Mac. Version 3.7 (“Indigo”) installs nicely in Lion and seems to work okay, but our household hasn’t put it to.

In instances where your Mac installations are no longer receiving updates due to this installation change (Delayed Updates and Immediate Update options above), a notification will automatically be displayed in Mac OSX telling the user to run the installer. Please refer to this documentation for ways to customize this notification.
If you have any questions about these options, please cancel this promote and submit a support request. We are more than happy to help you with your upgrade process!

eclipse.org went with a mountain peaks as the website theme for the release of Photon. Fun and fitting. The Eclipse site prompted me about the cookie use policy. Another change since last year, but not unexpected.

The matrix comparing the packages is still clear. The Java version is a subset of the Java EE version. I chose the later since it has the JavaScript tools built in. Unlike the last few years, a sponsored/commercial version wasn’t featured prominently. In fact, I didn’t notice one at all. Vaadin and JRebel do show as sponsored/promoted plugins in Eclipse Marketplace though so no risk forgetting about them!

Installing

I like to download and install a fresh Eclipse so I don’t have random plugins I’ve tried throughout the year. I downloaded the installer first which is a nice small, well relatively small, (55MB) file. I choose “Eclipse IDE for Java EE Developers” and an installation folder. This took a few minutes. I saw messages go by about it being slower than usual to download Eclipse plugins from various servers. Presumably because Photon has only been out a few days and lots of people are downloading.

How To Install Eclipse On Mac OS X

I got a prompt from Oomph to accept /plugins/org.eclipse.rse.ui_3.3… as unsigned content. I accepted, but was a little surprised.

Then I was able to open Eclipse

Installing the plugins

See Full List On Eclipse.org

Already installed were:

• m2e (maven)
• BuildShip (gradle)
• EclEmma (code coverage)
• JUnit (3, 4 and 5)
• eGit (git)

The significant plugins I chose to re-install are listed in this table.

Plugin	Purpose
Eclipse Tomcat Plugin	One click launch for recent versions of Tomcat. (This is the successor to Sysdeo and Mongrel) Problem/resolution I got a PKIX error. But clicking through it still allowed me to install so I didn’t have to update the certs or anything. Unable to read repository at https://devtools.his.de/tomcatplugin/updatesite/content.xml. sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target This is a known issue. In my case, it was caused by the eclipse.ini automatically picking up my Java 11 early access install. After changing it to point to Java 8, things went better. This allowed it to pick up the cryptography jars and work as expected.
SonarLint	I reply heavily on SonarLint. It gives you static analysis findings in Eclipse. I also included the SonarLint Java Configuration Helper so it can see the version of Java I am using. (I”m on Java 8 right now so this is redundant at the moment. But I’m ready for when Java 9 comes out.)
Subclipse	I trouble with Subversive in Eclipse Oxygen so I switched to Subclipse. I would have needed to switch this year regardless as Subversive is no longer supported.
Eclipse Memory Analyzer	For finding memory leaks.
Freemarker IDE	Freemarker syntax highlighting and macro assistance. Unlike with Eclipse Oxygen, this worked on the first install attempt.
Pydev	Python plugin/perspective
Contrast	To spot potential security issues. See my impressions of the Contrast plugin.
Bytecode Outline	I’ve been looking at bytecode a good fit for the book to make sure I understand why things are happening. This plugin makes it easy. The version number has hex towards the end; maybe the number from github?
Pitclipse	For mutation testing coverage

What excites me

1. When searching using open resource/type, exact matches take precedence (vs files you looked at with similar name.) Also, it now shows the path in the workspace regardless of whether the filename is a duplicate. Both are nice usability improvements.
2. The UI changed for the debugger. I like that you can see more variables in the debugger view without having to scroll or resize the window.
3. There’s now a workspace option to “Sort library entries alphabetically in Package Explorer”. This makes it easier to find things than the default order (which is the classpath.)

What I didn’t like

1. On Mac, the default font changed from Monaco to Menlo so keywords show in bold instead of just color. This was more of a “change is hard” thing. The first day, I didn’t like the new bolding. I wasn’t used to it so the keywords looked different. By the second day, I was used to it and it was just readable as the original. (I know I could have changed my workspace default back to Monaco if I continued to not like it).

Other interesting features

1. Eclipse now supports Rust. I haven’t used it, but Rust is supposed to be an up and coming language.
2. Eclipse supports Java 10 out of the box. Not that interesting because Java 10 came out in March. But good to know that Eclipse is staying current. I imagine there will be an Eclipse 4.8.1a in September or October for Java 11 support since Java 11 comes out in September. Eclipse did this for JUnit 5 so there is definitely precedent.
3. JUnit 5 is included. This doesn’t excite me because I had been using 4.7.1a which also had JUnit 5 support. But if you are upgrading from the release a year ago, it is definitely exciting!
