Building S1TBX from the source

  1. Download and install the required build tools

    • Install J2SE 1.8 JDK and set JAVA_HOME accordingly.
    • Install Maven and set MAVEN_HOME accordingly.
    • Install git
  2. Add $JAVA_HOME/bin and $MAVEN_HOME/bin to your PATH.

  3. Clone the S1TBX source code and related repositories into SNAP/

    git clone
    git clone
    git clone
    git clone
  4. CD into SNAP/snap-engine:

    mvn clean install

  5. CD into SNAP/snap-desktop:

    mvn clean install

  6. CD into SNAP/s1tbx:

    mvn clean install

  7. If unit tests are failing, you can use the following to skip the tests

    mvn clean install -Dmaven.test.skip=true

Setting up IntelliJ IDEA

  1. Create an empty project with the SNAP/ directory as project directory

  2. Import the pom.xml files of snap-engine, snap-desktop and s1tbx as modules. Ensure not to enable the option 'Create module groups for multi-module Maven projects'. Everything can be default values.

  3. Set the used SDK for the main project. A JDK 1.8 or later is needed.

  4. Use the following configuration to run SNAP in the IDE:

    • Main class: org.esa.snap.nbexec.Launcher

    • VM parameters: -Dsun.awt.nopixfmt=true -Dsun.java2d.noddraw=true -Dsun.java2d.dpiaware=false All VM parameters are optional

    • Program arguments: --clusters "E:\build\SNAP\s1tbx\s1tbx-kit\target\netbeans_clusters\s1tbx";"E:\build\SNAP\s1tbx\s1tbx-kit\target\netbeans_clusters\rstb" --patches "E:\build\SNAP\snap-engine\$\target\classes";"E:\build\SNAP\s1tbx\$\target\classes";"E:\build\SNAP\s1tbx\rstb\$\target\classes"

    • Working directory: SNAP/snap-desktop/snap-application/target/snap/

    • Use classpath of module: snap-main
