[javac] warning: bootstrap class path not set in conjunction with -source 1.7

[kalimero0073]

Dear community,

I receive following compiler problem when running one newly created plugin's build.xml:

[javac] warning: bootstrap class path not set in conjunction with -source 1.7

[javac] (use -source 8 or higher to enable lambda expressions)

I configured my computer and eclipse to use jdk 1.8, but although I can use lambda expressions in the IDE it does not compile with ant.

kind regards, Kale

Hi, if you open the commandline (e.g. "cmd") and type java -version what is the result? It should something like java version "1.8....

[kalimero0073]

C:>java -version java version "1.8.0_192" Java(TM) SE Runtime Environment (build 1.8.0_192-b12) Java HotSpot(TM) 64-Bit Server VM (build 25.192-b12, mixed mode)

Ok, thanks, that's strange. What if you try to start ant run in the base directory of AsTeRICS Grid within the commandline, not the IDE? Same error?

What about JAVA_HOME? Does this need to be setup correctly as well?

These are my environemnt variables: 1) JAVA_HOME: http://prntscr.com/sb8h3b 2) PATH for ant: http://prntscr.com/sb8ht5 3) PATH for java: http://prntscr.com/sb8i8t

JAVA_HOME C:\Tools\Java\jdk1.8.0_192_32bit ANT_HOME C:\Tools\apache-ant-1.10.5-bin\apache-ant-1.10.5 Path for ant: C:\Tools\apache-ant-1.10.5-bin\apache-ant-1.10.5\bin PATH for java: C:\Tools\Java\jdk1.8.0_192_32bit\bin

the error links me to the plugin's build.xml <target name="compile" depends="init" description="compile the source "> <javac source="${javac.source}" target="${javac.target}" includeantruntime="false" srcdir="${src.java}" destdir="${build}" verbose="true" debug="${debug}" classpath="${classpath}"> <classpath refid="asterics.classpath"/> </javac> </target>

So I thought there may be some default jdk value set somewhere, but I cannot localize it.

Hmm, the only difference I see is PATH for java on my system is .../jre/bin but for compiling this shouldn't make a difference?!

Otherwise unfortunately don't have more ideas, maybe @deinhofer ?

warning: bootstrap class path not set in conjunction with -source 1.7 is only a warning, so maybe things nevertheless work?

[kalimero0073]

I hardcoded it into the build file and it works now <target name="compile" depends="init" description="compile the source "> <javac source=**"1.8"** target=**"1.8"** includeantruntime="false" srcdir="${src.java}" destdir="${build}" verbose="true" debug="${debug}" classpath="${classpath}"> <classpath refid="asterics.classpath"/> </javac> </target>

Thank you for you help! I very much appreciate it.... Kind regards, Kale
