How to identify the Jdk version ???
Hi All,
I use Maven 2.2.1 and it runs on JDK 1.5 and above, but my source code is
not 1.5 compatible yet, so i configured my compiler plugin as shown below.
Everything works fine. but when i look into MANIFEST.MF of my jar file it
shows Build-Jdk: 1.5.0_13. So how do i confirm that my code were compiled
with 1.4 only not with 1.5 ??
Please Help
....
.....
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<verbose>true</verbose>
<executable>C:\JDK\ibm-jdk-1.4\bin\javac</executable>
<compilerVersion>IBM-JDK-1.4</compilerVersion>
Thanks
Jan

Short answer is: nope
Long answer is: it depends...
if you can get maven-toolchains-plugin released (I might do that once
my apache commit access is set up) then you could write a plugin that
queries the current toolchain and sets properties to the vesion of
java specified in the current tool chain. That would allow you to
specify the compiler config via toolchains and also additionally you
would be querying the same toolchain in your (to be written) property
setting plugin. Then the properties would be available for subsequent
plugin executions attached to the lifecycle.
Otherwise, if you define your compile config using properties, you
could get the properties that way...
Otherwise, you could use exec-maven-plugin or maven-antrun-plugin to
invoke the javac (specified by your property defining the path to the
java home you want to compile with) with -version and then parse the
output and put it into a properties file which you can then load...
using properties-maven-plugin.

Re: How to identify the Jdk version ???
Posted by raghu guru <ra...@gmail.com>.
Onc eagain Thanks for reply,
May be i tell you what i exactly i want, lets see if you have any idea on
this.
Basically i want to include change my MANIFEST.MF something like
Compiler:IBM-JDK-1.4
Compiler-Path:C:\JDK\ibm-jdk-1.4\bin\javac
So i included in jar pluging something like
<Compiler>${maven.compiler.compilerVersion}</Compiler>
<Compiler-Path>${maven.compiler.executable}</Compiler-Path>
but what i'm getting in my MANIFEST is
Compiler: null
Compiler-Path: null
so now is there any other properties to get these value?

Re: How to identify the Jdk version ???
Posted by Stephen Connolly <st...@gmail.com>.
essentially you can even compile with java 1.6 and use the 1.3 runtime
libraries and source 1.3 and target 1.3 and the resulting classes will
be just as good as compiling with java 1.3
the real issue you have is ensuring that the class and method
signatures that you have used in your code are only those for 1.4 or
earlier
that is where either a full set of unit tests or something like animal-
sniffer comes in.
unfortunately I have not released animal-sniffer from codehaus *yet*
so you'd have to use the original version from java.net
if you can wait a short while org.codehaus.mojo:animal-sniffer-maven-
plugin and you can use that (short time is a week or two)

Thanks Again,
Is there any properties available that shows compiled with 1.4, may be if
its available i want to include into MANIFEST.MF
or is there a way to just confirm it

sorry, I missed your pom snippet on this small screen
your classes were compiled with java 1.4
your jar was packaged up by a java 1.5 jre

thanks for replying
is this means, that configuring compiler version / executable in compiler
plugin will not have any effect on this??
i thought by classes are compiled with javac mentioned in executable tag..

Re: How to identify the Jdk version ???
Posted by Stephen Connolly <st...@gmail.com>.
your code was compiled with java 1.5 in compatibility mode for 1.4
providing you have only used classes and methods only from the 1.4
runtime libraries, everything will be fine
you need to use another tool to ensure that you have not accidentally
used some 1.5 methods (eg String.isEmpty())
animal-sniffer is one tool to do this check for you
