Maven Javadoc Plugin During Site Goal: javadoc: error - java.lang.OutOfMemoryError: Please increase memory -


i have been struggling increase memory of javadoc plugin via pom file. reason mac build slave fails during site goal outofmemoryerror. tried adjusting maxmemory of javadoc plugin via pluginmanagement section of pom (as per maven-javadoc-plugin documentation):

... <build>   ...   <pluginmanagement>     <plugins>       ...       <plugin>         <groupid>org.apache.maven.plugins</groupid>         <artifactid>maven-javadoc-plugin</artifactid>         <version>2.8.1</version>         <configuration>           <maxmemory>512m</maxmemory>         </configuration>       </plugin>     </plugins>   <pluginmanagement>   ... </build> ...

this didn't seem anything, build still failed out of memory error.

so decided put directly in plugin declaration instead (see build-plugins-plugin section below:

... <build>   ...   <pluginmanagement>     <plugins>       ...       <plugin>         <groupid>org.apache.maven.plugins</groupid>         <artifactid>maven-javadoc-plugin</artifactid>         <version>2.8.1</version>       </plugin>       ...     </plugins>   <pluginmanagement>   <plugins>     ...     <plugin>       <groupid>org.apache.maven.plugins</groupid>       <artifactid>maven-javadoc-plugin</artifactid>       <configuration>         <maxmemory>512m</maxmemory>       </configuration>     </plugin>     ...   </plugins>   ... </build> ...

...and yet still not working, mac build slave still fails during site goal.

it turned out being idiot. site goal uses plugin defintions declared in reporting section of pom. therefore had add max memory configuration here instead, see below:

... <build>   ...   <pluginmanagement>     <plugins>       ...       <plugin>         <groupid>org.apache.maven.plugins</groupid>         <artifactid>maven-javadoc-plugin</artifactid>         <version>2.8.1</version>       </plugin>     </plugins>   <pluginmanagement>   ... </build> ... <reporting>   <plugins>     <plugin>       <groupid>org.apache.maven.plugins</groupid>       <artifactid>maven-javadoc-plugin</artifactid>       <version>2.8.1</version>       <configuration>         <maxmemory>512m</maxmemory>       </configuration>     </plugin>   </plugins> </reporting> ...

based on result, assumption maven not pick configuration details defined in build-pluginmanagement section of pom plugins defined in reporting section. cheers.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
