Understanding OSGI Bundle states

Eclipse runs on top of the OSGi runtime, which manages the bundles (components) that make up an application. At any time, each bundle has one of these lifecycle states:

Bundle States:

  • Not in the list - If your bundle isn't in the list, then OSGi doesn't know anything about it. See the next section for debugging this problem.
  • INSTALLED - This means that OSGi knows about your bundle but there is something wrong and it couldn't resolve. Problems may include thing from missing dependencies to requiring a higher Java VM version than you are running with. To get more information on why your bundle is not resolved try running the diag <bundle id> command, where <bundle id> is your bundle id or bundle symbolic name.
  • RESOLVED - If your bundle is resolved but you expected it to be started, then try starting your bundle from the command-line with the start 123 command. If it won't start, then you should get some feedback as to what the problem is.
  • <<lazy>> - This means your bundle is resolved and is marked to be lazy started. Everything should be ok.
  • ACTIVE - your bundle is resolved and has been started, everything should be working as planned.

(source: OSGi Service Platform – Core Specification)

For example: I want to check the bundle states for my company plugins so I will use the below command.

osgi> ss com.espressif

"Framework is launched."

id State       Bundle

6 RESOLVED    com.espressif.idf.branding_1.2.0.qualifier

How to change a default Java version in macOS X

Let me check the current Java version
$ java -version
java version "13.0.2" 2020-01-14
Java(TM) SE Runtime Environment (build 13.0.2+8)

In macOS Java is installed as part of /Library/Java/JavaVirtualMachines folder.

Let me go there.
$ cd /Library/Java/JavaVirtualMachines/

I want to set Java 11 as the default Java version. Let me check what all I've installed in my system.
$ pwd

$ ls
jdk-11.0.7.jdk jdk-13.0.2.jdk jdk1.8.0_201.jdk

Let me set the default Java version to jdk-11.0.7.jdk
$ export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-11.0.7.jdk/Contents/Home/
$ export PATH=$JAVA_HOME/bin:$PATH

The above changes are applicable only for the current shell. To change permanently for all the shells you need set those two lines in the .bash_profile

First, go to the user home directory to run the below command
$ cd ~

$ pwd

$vim .bash_profile

Append the above two lines in the .bash_profile at the end, and save and exit.

All set.

Check again!

$ java --version
java 11.0.7 2020-04-14 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.7+8-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.7+8-LTS, mixed mode)

Good to go!!

Eclipse CDT based products

For my reference, I found this article very useful.

Espressif joined the league by providing the Eclipse Plugin for ESP-IDF for developing ESP32 IoT applications.

IoT Embedded CDT

(Eclipse CDT+ GNU MCU Eclipse) is shaping up as an "Eclipse Embedded CDT"

Eclipse Team is planning to put together eclipse CDT and gnu mcu eclipse plugins as a single package so that it will be easy for IoT and Embedded developers - they can just download a single package and get started with IoT.
