Building Apache Camel
Hello,
I just tried building Apache Camel to get a jar.
According to the documentation you have to execute these two lines:
$ export MAVEN_OPTS="-Xms3000m -Xmx3000m -XX:MaxPermSize=512m"
$ mvn clean source:jar install -Pfastinstall
Unrecognized VM option 'MaxPermSize=512m'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
I use openjdk version "17.0.4" 2022-07-19.
Do I need an older java version or is the MaxPermSize option different different in java 17?
Thanks in advance.
Greetings
Björn Försterling

The MaxPermSize option has been deleted as of Java 17 (in Java 16 this is marked as obsolete).
You should either remove it or change it to MaxMetaspaceSize.
According to the Java Docs:
-XX:MaxPermSize=size
Sets the maximum permanent generation space size (in bytes). This option was deprecated in JDK 8 and superseded by the -XX:MaxMetaspaceSize option.

You can either build with OpenJDK 11 with the option or build it with
OpenJDK 17 without the option.
The option:
-XX:MaxPermSize=size
Was already deprecated for a while and has been removed in Java 17.

Hi
That website info is a bit outdated as today these settings are automatic
set in the .mvn sub folder of the source code, eg see the file
.mvn/jvm.confiig
.mvn/jvm.config
-Xmx3584m -Djava.awt.headless=true -XX:+UseG1GC -XX:+UseStringDeduplication
So you dont need to tweak just use mvn clean install -P fastinstall
