Eclipse Ide For Java Developers Oxygen.3a Release (4.7.3a)
Maricel Fergason
With the first quarterly simultaneous release the naming scheme was changed: Photon, which was released in June, is followed by 2018-09 in September now. Many thanks to all the heroes who made the Eclipse IDE a bit better again!
I have made two short videos each for Photon three months ago and now for 2018-09, showing Eclipse IDE improvements in action: one about general and Git improvements and the other exclusively for Java developers. Below the two videos, you will find a list of the improvements with time stamps and links to details. If you dislike something, let me know what you want me to change next time (for example, if you prefer one longer video like before instead of several short videos like the current ones).
Several Eclipse 2018-09 IDE packages are available for download. Since Photon there has existed an Latest Eclipse Release update site in Window > Preferences: Install/Update > Available Software Sites. If you enable it, you can upgrade to 2018-09 via Help > Check for Updates. If automatic updates (Window > Preferences: Install/Update > Automatic Updates) have not been disabled, a dialog will ask you on December 19 if you want to upgrade to 2018-12.
Three weeks after the Oxygen.3 and the Java 10 release, Oxygen.3a now adds official support for Java 10 which was previously offered only as a pre-release via the Eclipse Marketplace. Because Oxygen.3a also contains some bug fixes, an upgrade is also recommended for Java developers who do not (yet) want to use Java 10.
Nonetheless, the Eclipse developers did a great job enhancing the Eclipse Java IDE to support var. The inferred type will be shown on mouse over and in the Javadoc view, the content assist is aware of the inferred type and offers the corresponding proposals and in Mark Occurences var is handled as a substitute for the inferred type:
For Java and other developers, several Eclipse Oxygen.3a IDE packages are available for download. Older versions of Oxygen will prompt you to upgrade to Oxygen.3a unless the built-in automatic update is disabled. Oxygen.3a is the last update for Eclipse Oxygen. Numerous major changes are currently being finalized for the next major release, Eclipse Photon, on June 27. If you want you can already test a pre-release of Eclipse Photon.
Eclipse Oxygen.3 is the last quarterly update of Oxygen. Thanks to everyone who has contributed in any way! Even if the main focus is already on Photon, which will be released on June 27, it is worth updating your Eclipse IDE (unless you want to test a pre-version of Photon instead).
Embedding the JDK into an Eclipse installation directory as jre subdirectory does not yet work, but as long as you do not start the Eclipse IDE from the command line from another directory you can use -vm with jre\bin\javaw.exe. To further improve the startup time, add the following two lines below -vmargs:
The cloning of a GitHub repository fails due to missing certificate authority (CA) certificates. You can fix this OpenJDK 9 issue by replacing the lib\security directory (which contains the cacerts file) with the same directory of an OpenJDK 10 early access build.
Oxygen.1a (4.7.1a) was released two weeks after Oxygen.1 (4.7.1) on October 11, 2017. Oxygen.1 includes bug fixes and minor improvements. Since Oxygen.1a, the Eclipse IDE runs out of the box with Java 9 and supports development for Java 9 as well as testing with JUnit 5. Many thanks to all of you who have contributed in any way.
Like last year, also this year the Eclipse simultaneous release was accompanied by a series of talks in which developers present their new developments (thanks Kat Hirsch for hosting it). Here is my summary of these six so-called webinars about Eclipse Oxygen; the first three are for IDE users, the other three about Eclipse frameworks:
If you have already seen my 10-minute Oxygen video, you can skip the first half on Eclipse Platform and Java development tools (JDT) improvements. If you watch the talk from the beginning, you can skip the part from 23:11 and 33:18, where the screen sharing is interrupted and afterwards some improvements are shown again. In the second half, Trace Points, which are missing in my video, are explained. Also Plug-in Development Environment (PDE) and the API Tooling improvements are demonstrated. I recommend Java developers to watch at least this and the following video. In addition, you might also watch the three-month old video of the Devoxx talk Eclipse 4.7 Platform News by Lars Vogel (23:38), which gives a deeper insight into some of the Platform, JDT and PDE improvements.
AsEclEmma became an Eclipse project, the Java IDE packages are shipped with built-in Java code coverage analysis now. This webinar gives a general introduction to EclEmma, but also shows how to use the Java Code Coverage feature to find unused code or JAR dependencies.
A nice trick is to find the code of a particular function of an application by differential code coverage: launch the application in coverage mode, reset already collected coverage data, execute the function and dump the coverage data. The code executed by the function is shown as covered. At the end of the webinar, some tips are given how common pitfalls can be avoided.
The webinar starts with the history of Xtext, a framework and tools to build and support domain-specific languages. Since Eclipse IDE lost market share, Xtext support has been extended to IntelliJ IDEA and will be extended to code editors and other IDEs via LSP. The Xtext language server is shown in action in the Eclipse IDE as well in Theia, a cloud and desktop IDE framework implemented in TypeScript. After the demos the new Xtext feature to generate trace code is explained.
These were the six Eclipse Oxygen webinars with a total duration of almost five hours, presented by ten people from all over the world. In case this is not enough, check out my Recommended Eclipse Videos playlist. If you have any recommendation for an Eclipse video, please drop a comment.
The six Oxygen webinars (each of them about 50 minutes long) provide or will provide a deeper insight. Java users are recommended to follow @EclipseJavaIDE on Twitter, which provides daily tips and tricks.
This plug-in lets you run your TestNG tests from Eclipse. You can run suites, groups or individual methods. Errors are reported in a separate tab that lets you jump to failing tests efficiently. The plug-in also contains several templates to create tests easily.
Is Eclipse MarketPlace is giving trouble, probably because of SSL certificate issue in java cacert or anything, you can do offline installation. I downloaded the zip file from testng github page /testng-team/testng-eclipse, get the folders features and plugins, and put it inside eclipse installation directory/dropins folder

Following advices in Internet, I tried to include TestNG System Library as Module dependencsy and then I removed the com.beust..... from exported modules and seems it start to launch, but get another error:
TestNG plugin is installed in Eclipse, yesterday Eclipse got some updates and ok confirmed the updates then TestNG stopped working. I uninstalled and installed it again but still not working i can't see it in run configurations.

I have followed the comments on the section to try and sort this error on my own, i have not found anything so far that works, gettting the below error, tried different also with version of Eclispe 2019-03
"Unable to read repository at //testng.org/testng-eclipse-update-site/content.xml.

I see the below error when I try to install the TestNG plugin in my Eclipse either via the marketplace directly or using the new testng-update URLs. Has anyone ever faced this issue before and have any idea as to how to resolve it? Any help would be really appreciated.

I am trying to install TestNG. The sites beust and lnkd.in/eQ9Z4Fx are not found and returns a 404. Tried downloading from TestNG page on Eclipse Market Place, but when tried to run the testNG program its showing error as its not compatible with eclipse 2020-12 version. Any other ideas from where to download testNG version which will work on eclipse 2020-12 #TestNG?
Hi, I tried installing TestnG from eclipse market place for Version: 2020-06 (4.16.0). But it shows TestNG version is not comaptible with this version of Eclipse.Even i tried using locations mentioned in previous posts.But shows same error couldn't find the file on these locations.Can anyone tell me which version of eclipse i should download or is there any workaround for this version?
for the link.... someone replied to my post and it worked for me "dl.bintray.com/testng-team/testng-eclipse-release/". Copy/Paste that in address bar without double quotes. Then click on "zipped", then click on latest version and click on next link in the next page.
Our team found that TestNG plugin is not available to be installed in eclipse. Team tried from both the options available in Help like Market place and New Software installation through "beust.com/eclipose". Even beust site is not responding on either private or Public network.
