Hi matus, When issuing make accessibility.all command, it actually building the whole source code. Right now I come to build 46 of 62, module ridljar, and the build was stop on this build. From the stack trace I see this <style type="text/css">  </style> javac: invalid source release: 1.7 I am currently using JAVA version 1.7 in my machine. It seems that JAVA 1.7 doesn't fit well. May I know which JAVA version should I use for the build? And is there a possibility that to set the specific JAVA version for the build without downgrading the system's JAVA version? Here is the full stack trace ============= (46/62) Building module ridljar ============= Entering /home/kokhoe/workspace/LibreOffice/core/offapi/prj gbuild module /home/kokhoe/workspace/LibreOffice/core/offapi: make -f Makefile -j1 -rs all slowcheck gb_PARTIALBUILD=T Entering /home/kokhoe/workspace/LibreOffice/core/ridljar/prj gbuild module /home/kokhoe/workspace/LibreOffice/core/ridljar: make -f Makefile -j1 -rs all slowcheck gb_PARTIALBUILD=T [build JVM] CustomTarget/ridljar/javamaker/done [build CUS] ridljar/javamaker [build JCS] Jar/ridl javac: invalid source release: 1.7 Usage: javac <options> <source files> use -help for a list of possible options make[2]: *** [/home/kokhoe/workspace/LibreOffice/core/workdir/<a href="http://unxlngx6.pro/JavaClassSet/Jar/ridl/done">unxlngx6.pro/JavaClassSet/Jar/ridl/done</a>] Error 2 [build DEP] IDL:offapi [build IDL] offapi/com/sun/star/animations/idl make[2]: *** No rule to make target `/home/kokhoe/workspace/LibreOffice/core/offapi/com/sun/star/auth/SSOExceptions.idl', needed by `/home/kokhoe/workspace/LibreOffice/core/workdir/<a href="http://unxlngx6.pro/UnoApiPartTarget/offapi/com/sun/star/auth/SSOManagerFactory.urd">unxlngx6.pro/UnoApiPartTarget/offapi/com/sun/star/auth/SSOManagerFactory.urd</a>'.
