I found this problem occurs if I use Java 9 but not if I use Java 8.
How can I install Eclipse to my computer to run Java 9?
Ubuntu 18.04 and later
The Eclipse snap package from the default Ubuntu repositories is perfect for Java programming because it is bundled with a Java development environment. To install it open the terminal and type:
sudo snap install eclipse --classic
This command will install the latest Photon Release 4.8 version of Eclipse IDE for Java Developers which was updated 8 days ago. Eclipse changed its codename policy so that Eclipse releases from September 2018 and onward are named after the year and month of the release date, for example Eclipse 2020-06. This naming scheme also applies to the eclipse snap package.
Eclipse Photon JDT supports Java 9 completely:
- The Eclipse compiler for Java (ECJ) implements all the new Java 9 language enhancements.
- Updated significant features to support Java Modules, such as compiler, search and many editor features.
Note:
In order to add a new Java version to Eclipse in 18.04 and later, for example openjdk-11-jdk, follow the instructions listed above in steps 1-9, only replace the string java-9-openjdk with the java version that you want to add to Installed JREs.
Ubuntu 17.10
I have installed Eclipse Oxygen (the latest version of Eclipse) and openjdk-9-jdk and Eclipse is working with openjdk-9-jdk in this version. If you want to keep openjdk-8-jdk as the default Java version to use in your new Eclipse Oxygen, you can open Eclipse and add openjdk-9-jdk from inside Eclipse as follows.
-
Select Window -> Preferences
-
In the pane on the right side of the Preferences window, click the black triangle to the left of Java to unfold it.
-
Double-click Installed JREs.
-
Click the Add on the left side of the preferences window to add a new JRE.
-
Select Standard VM and click Next.
-
In the JRE Home: field type
/usr/lib/jvm/java-9-openjdk-amd64(or i386 instead of amd64 for 32-bit Eclipse) -
In the JRE Name: field type
java-9-openjdk-amd64(or i386 instead of amd64 for 32-bit Eclipse) -
Click the Apply button.
-
Now in Installed JREs in Step 3. you can click the checkbox to the left of a JRE in the list of installed JREs to select it as the default and click the Apply button to apply the change in the default Installed JRE.
The same instructions do not work for the default version of Eclipse in Ubuntu 16.04.
-
You have to install the
openjdk-8-jre:sudo apt-get install openjdk-8-jre -
Next switch to the jre-8 version:
$ sudo update-alternatives --config java There are 2 choices for the alternative java (providing /usr/bin/java). Selection Path Priority Status * 0 /usr/lib/jvm/java-9-openjdk-amd64/bin/java 1091 auto mode 1 /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java 1081 manual mode 2 /usr/lib/jvm/java-9-openjdk-amd64/bin/java 1091 manual mode -
check java version:
$ java -version openjdk version "1.8.0_151" OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-0ubuntu0.17.10.2-b12) OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode) start eclipse
