The Hibernate 5.4 runtime provider now incorporates Hibernate Core version 5.4.7.Final and Hibernate Tools version 5.4.7.Final.

The Hibernate 5.3 runtime provider now incorporates Hibernate Core version 5.3.13.Final and Hibernate Tools version 5.3.13.Final.

The new Quick Search dialog provides a convenient, simple and fast way to run a textual search across your workspace and jump to matches in your code. The dialog provides a quick overview showing matching lines of text at a glance. It updates as quickly as you can type and allows for quick navigation using only the keyboard. A typical workflow starts by pressing the keyboard shortcut Ctrl+Alt+Shift+L (or Cmd+Alt+Shift+L on Mac). Typing a few letters updates the search result as you type. Use Up-Down arrow keys to select a match, then hit Enter to open it in an editor.

You can now save the active editor even when the Project Explorer has focus. In cases where an extension contributes Saveables to the Project Explorer, the extension is honored and the save action on the Project Explorer will save the provided saveable item instead of the active editor.

The Show In context menu is now available for an element inside a resource project on the Project Explorer.

In simple cases such as a 2-way comparison or a 3-way comparison with no merges and conflicts, the Compare Viewer now shows different colors, depending on whether text has been added, removed or modified. The default colors are green, red and black respectively.

The colors can be customized through usual theme customization approaches, including using related entries in the Colors and Fonts preference page.

The status line for Text Editors now shows the cursor position, and when the editor has something selected, shows the number of characters in the selection as well. This also works in the block selection mode.

These two new additions to the status line can be disabled via the General > Editors > Text Editors preference page.

Several dialog texts have been shortened. This allows you to capture the important information faster.

Previously

Now

In the Project Explorer, you can now close a project using middle-click.

In the Environment Tab of the Launch Configuration dialog, you can now double-click on an environment variable name or value and start editing it directly from the table.

Right-clicking on the environment variable table now opens a context menu, allowing for quick addition, removal, copying, and pasting of environment variables.

The External Tools Configuration dialog for launching an external program now supports the Show Command Line button.

The preference to close editors automatically is now enabled by default. It will be triggered when you have opened 99 files. If you continue to open editors, old editors will be closed to protect you from performance problems. You can modify this setting in the Preferences dialog via the General > Editors > Close editors automatically preference.

You can now see all the colors currently being used in Text Editors from the Appearance color options table, located in the Preferences > General > Editors > Text Editor page.

The Eclipse SDK has been configured to show stack traces for UI freezes in the Error Log view by default for new workspaces. You can use this information to identify and report slow parts of the Eclipse IDE.

You can disable the monitoring or tweak its settings via the options in the General > UI Responsiveness Monitoring preference page as shown below.

On Linux and Mac, Eclipse can now start automatically in dark theme when the OS theme is dark. This works by default, that is on a new workspace or when the user has not explicitly set or changed the theme in Eclipse.

More and more operating systems provide a system wide dark theme. Eclipse now respects this system wide theme setting when the Eclipse help content is displayed in an external browser. A prerequisite for this is a browser that supports the prefers-color-scheme CSS media query.

As of writing this the following browser versions support it:

The Help System as well as the help content of the Eclipse Platform, the Java Development Tooling and the Plug-in Development Environment now use high resolution icons. They are now crisp on high resolution displays and also looks much better in the dark theme.

Labels, Sections, Checkboxes, Radio Buttons, FormTexts and Sashes on forms now use the correct background color in the dark mode on windows.

Interactive performance has been further improved in this release and several UI freezes have been fixed.

For presentations, screen casts and learning purposes, it is very helpful to show the corresponding key binding when a command is invoked. When the command is invoked (via a key binding or menu interaction) the key binding, the command’s name and description are shown on the screen.

You can activate this in the Preferences dialog via the Show key binding when command is invoked check box on the General > Keys preference page. To toggle this setting quickly the command 'Toggle Whether to Show Key Binding' can be used (e.g. via the quick access).

Java 13 is out and Eclipse JDT supports Java 13 for 4.13 via Marketplace.

The release notably includes the following Java 13 features:

Please note that these are preview language feature and hence enable preview option should be on. For an informal introduction of the support, please refer to Java 13 Examples wiki.

The Eclipse Console view currently can not ensure that mixed standard and error output is shown in the same order as it is produced by the running process. For Java applications the launch configuration Common Tab now provides an option to merge standard and error output. This ensures that standard and error output is shown in the same order it was produced but at the same time disables the individual coloring of error output.

The Java quickfix/cleanup Convert to enhanced 'for' loop is now offered on for loops that are iterating through Collections. The loop must reference the size method as part of the condition and if accessing elements in the body, must use the get method. All other Collection methods other than isEmpty invalidate the quickfix being offered.

A Java quickfix is now offered to initialize an uninitialized final field in the class constructor. The fix will initialize a String to the empty string, a numeric base type to 0, and for class fields it initializes them using their default constructor if available or null if no default constructor exists.

Use Autoboxing and Unboxing when possible. These features are enabled only for Java 5 and higher.

Remove redundant modifier now also removes useless abstract modifier on the interfaces.

For the given code:

You get this:

Adding a Javadoc comment to a Java module (module-info.java) will result in automatic annotations being added per the new module comment preferences.

The $(tags) directive will add @uses and @provides tags for all uses and provides module statements.

Code assist for "Chain Template Proposals" will be available. These will traverse reachable local variables, fields, and methods, to produce a chain whose return type is compatible with the expected type in a particular context.

The preference to enable the feature can be found in the Advanced sub-menu of the Content Assist menu group (Preferences > Java > Editor > Content Assist > Advanced) .

All the settings in the Blank lines section can now be configured to remove excess blank lines, effectively taking precedence over the Number of empty lines to preserve setting. Each setting has its own button to turn the feature on, right next to its number control. The button is enabled only if the selected number of lines is smaller than the Number of empty lines to preserve, because otherwise any excess lines are removed anyway.

There’s quite a lot of changes in the Blank lines section of the formatter profile.

Some of the existing subsections and settings are now phrased differently to better express their function:

More importantly, a few new settings have been added to support more places where the number of empty lines can be controlled:

Most of the new settings have been put in a new subsection Blank lines within method/constructor declarations.

JUnit 5.5.1 is here and Eclipse JDT has been updated to use this version.

The Java Launch Configuration now supports patching of different modules by different sources during the launch. This can be verified in the Override Dependencies…​ dialog in the Dependencies tab in a Java Launch Configuration.

Manually changing the settings file .settings/org.eclipse.jdt.core.prefs of a project will result in a full project build, if the workspace auto-build is on. For example, pulling different settings from a git repository or generating the settings with a tool will now trigger a build. Note that this includes timestamp changes, even if actual settings file contents were not changed.

For the 4.13 release, it is possible to disable this new behavior with the VM property: -Dorg.eclipse.disableAutoBuildOnSettingsChange=true. It is planned to remove this VM property in a future release.
