Ant Use -source 7 Or Higher To Enable Diamond Operator
Solution 1:
You need to set java.source
and java.target
. Either via -D
:
ant release -Djava.source=7 -Djava.target=7
Or put it in ant.properties
in your project:
# ant.properies contents:
java.source=7
java.target=7
Solution 2:
Solved it if anyone else is stuck on this one.
I had to change <import file="${sdk.dir}/tools/ant/build.xml"/>
file.
There are properties
<property name="java.target" value="1.5" /> <property name="java.source" value="1.5" />
and the values should be changed to 1.7
Solution 3:
Heisenberg's solution is correct (kudos and +1...) but not clean: you don't have to change the master build.xml
file (bad!), what you need is to add the lines he suggested:
<property name="java.target" value="1.7" />
<property name="java.source" value="1.7" />
right before the line
<import file="${sdk.dir}/tools/ant/build.xml" />
in the local build.xml
file, and the default options will be overridden.
Hope it helps!
Solution 4:
Just to clarify, I changed my ant.properties
as follows:
java.target=1.7
java.source=1.7
Making changes in build.xml before the above suggested line didn't work for me for some reason.
