The initial analysis suggests that there is issue related to jdk 11 on the Travis build platform.

branch travis-build-issue-9-19-2022 is created in github, which is dedicated to the investigation and analysis for this issue.

After tracking and reading the script, the initial judgement is that there is missing file at https://github.com/sormuras/bach/raw/releases/11/install-jdk.properties. This file is used in the script install-idk.sh script, which, in turn, in used in the travis build yml file.

I create a file "zhan-install-jdk.properties" in branch travis-build-issue-9-19-2022. This file will serve script install-jdk.sh, which, in turn, is used in the yml file.

Adding file "zhan-install-jdk.properties" in branch travis-build-issue-9-19-2022 and modifying script install-jdk.sh is to solve the jdk issue exposed in the failed travis build#389, which is mentioned at the beginning of this github issue. There is another error also revealed in the failed travis build#389, and this error is related to sonar. We can see these two errors in the log generated from the travis build#389. See below.

$ bash $TRAVIS_BUILD_DIR/install-jdk.sh -F 11 --target $JAVA_HOME
install-jdk.sh 2020-06-02
Couldn't determine a download url for 11-GPL on linux-x64
The command "bash $TRAVIS_BUILD_DIR/install-jdk.sh -F 11 --target $JAVA_HOME" exited with 1.
0.01s$ mvn sonar:sonar -Popenwis,admin,user -Dsonar.projectKey=OpenWIS_openwis
The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
NB: JAVA_HOME should point to a JDK not a JRE
The command "mvn sonar:sonar -Popenwis,admin,user -Dsonar.projectKey=OpenWIS_openwis" exited with 1.

The jdk issue in the failed travis build#389, mentioned at the beginning of this github issue, is solved. This can be seen in the travis build#400. I will move to another error that was also in travis build#389. This error is related to sonar.
