I have problems with the build of the apache openjpa 2.2.0 examples and Java
7 because of
any idee how to solve that?
[javac]
C:\apache-openjpa-2.2.0-SNAPSHOT\examples\openbooks\build.jse.xml:81
: warning: 'includeantruntime' was not set, defaulting to
build.sysclasspath=las
t; set to false for repeatable builds
[javac] Compiling 46 source files to
C:\apache-openjpa-2.2.0-SNAPSHOT\exampl
es\openbooks\target\classes
[javac] warning: Supported source version 'RELEASE_6' from annotation
proces
sor 'org.apache.openjpa.persistence.meta.AnnotationProcessor6' less than
-source
'1.7'
Bei switching JAVA_HOME to Java 7 all works fine
another problem with th Classloader (did ORACLE change behaviour?) with
example simple\hellojpa
compile:
[javac] C:\apache-openjpa-2.1.0\examples\simple\build.xml:104: warning:
'inc
ludeantruntime' was not set, defaulting to build.sysclasspath=last; set to
false
for repeatable builds
run:
