Hi, I recently posted the following message to eclipse.newcomer, but
Daniel Megert suggested to state the question here (I think). S here it
goes:
I have a rather complicated project with a lot of generics. I struggled
hard to get rid of all warnings and error messages in Eclipse. Now, if
I try to compile the same project from the command line, I get a whole
bunch of error messages, mostly concerning generics (and quite a few ‘No
such symbol’ errors). Is there a way to tell Eclipse it should use the
javac compiler, or to have it use the same rules/strictness?
Thanks,
H.

No, Eclipse can not use javac (for good reason).
Eclipse is a spec-compliant compiler, so if you find some cases where it
does not meet the spec, you should report the details as a bug against
Eclipse JDT.
Having said that, I suspect you are simply not using javac correctly.
Perhaps your system has more than one JDK installed and your
command-line compile is inadvertently using a pre-1.5 version? OR do you
have a system CLASSPATH setting that could be causing conflicts with javac?
What is the javac command-line you are trying? What, if anything, is
your system CLASSPATH? What is the result of "java -version"?

Hope this helps,

It can if you are willing to loose all the additional features. Simply
register an Ant task using javac as builder instead of the 'Java
Builder' (see 'Builders' project property page).

OK, this works, but isn’t really helpful, as the errors reported by
javac are not shown in the source. So no, I am not willing to loose all
the additional features...

I don’t want to be provocative, but I vaguely remember a thread in
comp.lang.java.(help|programmer) where somebody claimed that his
experience was that whenever eclipse and javac differ in meaning, javac
is right, following the experts. Ah, I found it:
http://groups.google.com/groups?as_umsgid=eeosou$6mm$1@news2 .kornet.net
>> Having said that, I suspect you are simply not using javac correctly.

Certainly not:
hendrik@lichtenstein:~/workspace/Jakarta> javac -version
javac 1.5.0_07
I tried with the ibm javac too:
hendrik@lichtenstein:~/workspace/Jakarta>
/usr/local/ibm-java2-x86_64-50/bin/javac -version
javac 1.5.0
It gives more or less the same errors.
>> OR do

env | grep CLASSPATH returns nothing
>> What is the javac command-line you are trying? What, if anything, is
>> your system CLASSPATH? What is the result of "java -version"?
I used a supplied build file with ant, but it comes down to this, which
give the same errors:
hendrik@lichtenstein:~/workspace/Jakarta>
/usr/local/ibm-java2-x86_64-50/bin/javac -Xlint:-deprecation -classpath
/home/hendrik/Java/Jakarta\ Commons\
Collections/commons-collections-generic-3.2-src/src/java
org/apache/commons/collections/*.java
(at will, remove /usr/local/ibm-java2-x86_64-50/bin)
And then:
org/apache/commons/collections/ClosureUtils.java:196: cannot find symbol
symbol : method
getInstance(org.apache.commons.collections.Closure<capture of ? super
I>,org.apache.commons.collections.Closure<capture of ? super I>)
location: class org.apache.commons.collections.functors.ChainedClosure
return ChainedClosure.getInstance(closure1, closure2);
^
and so on. (I am sure the method is there, btw.)
It fails with 20 errors. There are generics involved in all of them.
I guess I’ll have to go error-hunting without Eclipse’s useful features
now...

Ok, I didn’t see that follow-up before.

I doubt it is the same javac, they give slightly different output messages:

Well, it is not so easy to isolate the problem, some hints would be
welcome on how to do that.

I slimmed it down to three classes, focusing on the first error I get.
The class ClosureUtils invokes ChainedClosure.getInstance(Closure<?
super I> closure1, Closure<? super I> closure2). Eclipse says this is
ok, javac gives:
hendrik@lichtenstein:~/workspace/test Java> javac -classpath
/home/hendrik/workspace/test\ Java/ collections/ClosureUtils.java
collections/ClosureUtils.java:8: <I>getInstance(collections.Closure<?
super I>,collections.Closure<? super I>) in
collections.functors.ChainedClosure cannot be applied to
(collections.Closure<capture of ? super I>,collections.Closure<capture
of ? super I>)
return ChainedClosure.getInstance(closure1, closure2);
^
1 error
I attach the three files, they should be put in a package ‘closure’.
Can I deliver it as a bug report like this, or is it still too complicated?
Thanks, H.

Please go there to enter a bug report:

Probably just different versions of the same implementation (different
points in time), try "javac -version".

FYI
158519 is another instance of the issue mentionned above on the Google
forums, and this is the same bug in Javac
@see http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6302954
158531 is also a known issue in Javac and the JLS
@see http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6369605
Note that we have already open issues for these, where we are watching
at the outcome of the Javac bugs to adjust our semantics. For the first
defect, our behavior is the expected one. One the second one, the spec
has to be addressed, and then we will adjust. We believe our current
behavior to be close to the final result (i.e. the code should be
accepted in the end, as we accept it today). But we need to wait until
the spec issue got resolved.

That’s what I thought, that these bugs existed already.

I do agree that Eclipse’s behaviour seems/feels correct, but it is
inconvenient, because I want to make an ant task to compile it outside of E.

This one is simpler <g>... you can use the Eclipse Java compiler
standalone, and it comes with an Ant Javac task adapter (either use
directly the JDT/Core plugin JAR org.eclipse.jdt.core_xxx.jar from your
Eclipse install, or grab a smaller subset conveniently packaged as
ecj.jar which contains the batch compiler and an Ant javac task adapter).
You can get ecj.jar directly from the Eclipse download page
e.g. for standalone batch compiler matching 3.2 version
http://download.eclipse.org/eclipse/downloads/drops/R-3.2-20 0606291905/download.php?dropFile=ecj.jar
Each time a new build is made available, a new version of ecj.jar is
posted as well.
For instruction on how to use the batch compiler either on command line
or through an Ant task, please read:
http://help.eclipse.org/help32/topic/org.eclipse.jdt.doc.isv /guide/jdt_api_compile.htm
Hope this helps, and feel free to ping us in case you do not succeed.
FYI - Eclipse drops are constructed using this very Ant adapter, so it
should work for you as well.

Thanks for the pointers, but as this isn’t my project, this is no
option. I am only a contributer. I will consider it for later projects
though.
