Eclipse starts GeoServer source project and solves problems

       I used Eclipse to start the project when I studied the GeoServer source code before. Today, I organized the cloud notes and ran the recently released GeoServer 2.13.0 source code step by step. GeoServer is an open source geographic information program based on java, which can easily publish and manage map data. For details, please visit the official website . Step by step:

1.jdk environment, jdk1.8.0 or above, set environment variables (Linux), vi ~/.bashrc, enter

export JAVA_HOME=/home/shanks/software/jdk1.8.0_161
export JRE_HOME=/home/shanks/software/jdk1.8.0_161/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH

2. Download the GeoServer source code and unzip it

3. Install Eclipse

4. Maven download, set environment variables

export MAVEN_HOME=/home/shanks/software/apache-maven-3.3.9
export PATH=$PATH:$MAVEN_HOME/bin

Command line execution source ~/.bashrc

5. Enter the src directory under the GeoServer source code project, and enter the command line:

mvn clean install -Dmaven.test.skip=true

6. Build the eclipse project

mvn eclipse:eclipse

7. Open eclipse, Import -> General -> Existing Projects into Workspace, import it

After the import is successful, the view is as follows:

8. Start the project

Find Start.java as shown below and run

After startup, you can open the web page in the browser: http://localhost:8080/geoserver/web.

GeoSever initial account: admin, password: geoserver, after opening:

9. When building the project, " Access restriction: The type 'RenderingEngine' is not API (restriction on ", etc. may appear , which can be resolved as follows:

Right-click on the project –>Properties->Java Build Path-->Libraries, find "JRE System Libraries", and click Remove.

Then click Add Library on the right, add "JRE System Libraries", and finally Apply.
