Maven snippet – add generated sources to the build

July 21, 2014 Leave a comment

Here’s a maven snippet I found myself looking for many times – adding generated sources to the build.
This tells Maven to include the generated classes as part of the compilation, which ensures any non generated code that depends on them compiles fine, and their corresponding .class files be included in the .jar/.war file.

  ...
  <build>
    <plugins>
      ...
      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>build-helper-maven-plugin</artifactId>
        <executions>
          <execution>
            <id>add-source</id>
            <phase>generate-sources</phase>
            <goals>
              <goal>add-source</goal>
            </goals>
            <configuration>
              <sources>
                <source>${project.build.directory}/generated</source>
              </sources>
            </configuration>
          </execution>
        </executions>
      </plugin>
    ...
    </plugins>
  </build>
  ...

In this case (line #153) – we assume that the sources are generated to target/generated.

Bash Epoch Converter

July 10, 2014 Leave a comment

I use the online epoch converter on an almost daily basis with an almost single usage – converting a value of seconds/milliseconds since the epoch (1/1/1970 00:00:00) to a human readable date.
I wanted something quicker which I can use from my Terminal window without – so I created a Bash function that performs that:

epoc usage

epoc usage


The function

epoc ()
{
    [[ $# == 0 ]] && SECONDS_SINCE_EPOCH=$(date +%s);
    [[ "$1" == "-h" ]] && printf "$(tput bold)$(tput setaf 1)Usage:$(tput sgr0) $(tput bold) epoc [<seconds-since-epoch|milli-seconds-since-epoch>]$(tput sgr0)\n$(tput bold)$(tput setaf 2)Examples:$(tput sgr0)\n\t$(tput bold)epoc 1404382131$(tput sgr0)\n\t$(tput bold)epoc 1404305405000\n" && return 1;
    [[ $# == 1 ]] && SECONDS_SINCE_EPOCH=$1;
    [[ $(printf ${SECONDS_SINCE_EPOCH} | wc -c) -gt 10 ]] && let SECONDS_SINCE_EPOCH=${SECONDS_SINCE_EPOCH}/1000;
    printf "\n$(tput bold)$(tput bold)$(tput setaf 2)%-20s\t| %-35s\t| %-35s$(tput sgr0)\n" "Seconds Since Epoch" "Time (Local)" "Time (GMT)";
    printf "%-20s\t| %-35s\t| %-35s\n\n" ${SECONDS_SINCE_EPOCH} "$(date -r ${SECONDS_SINCE_EPOCH} '+%d-%h-%Y %H:%M:%S %Z (%z)' | sed 's/(+\([0-9][0-9]\)/(+\1:/')" "$(export TZ=GMT; date -r ${SECONDS_SINCE_EPOCH} '+%d-%h-%Y %H:%M:%S %Z (%z)' | sed 's/(+\([0-9][0-9]\)/(+\1:/')"
}
epoc ()
{
    [[ $# == 0 ]] && SECONDS_SINCE_EPOCH=$(date +%s);
    [[ "$1" == "-h" ]] && printf "$(tput bold)$(tput setaf 1)Usage:$(tput sgr0) $(tput bold) epoc [<seconds-since-epoch|milli-seconds-since-epoch>]$(tput sgr0)\n$(tput bold)$(tput setaf 2)Examples:$(tput sgr0)\n\t$(tput bold)epoc 1404382131$(tput sgr0)\n\t$(tput bold) epoc 1404305405000\n" && return 1;
    [[ $# == 1 ]] && SECONDS_SINCE_EPOCH=$1;
    [[ $(printf ${SECONDS_SINCE_EPOCH} | wc -c) -gt 10 ]] && let SECONDS_SINCE_EPOCH=${SECONDS_SINCE_EPOCH}/1000;
    printf "\n$(tput bold)$(tput bold)$(tput setaf 2)%-20s\t| %-35s\t| %-35s$(tput sgr0)\n" "Seconds Since Epoch" "Time (Local)" "Time (GMT)";
    printf "%-20s\t| %-35s\t| %-35s\n\n" ${SECONDS_SINCE_EPOCH} "$(date -d @${SECONDS_SINCE_EPOCH} '+%d-%h-%Y %H:%M:%S %Z (%:z)')" "$(export TZ=GMT; date -d @${SECONDS_SINCE_EPOCH} '+%d-%h-%Y %H:%M:%S %Z (%:z)')"
}
