Dotaz: commons-net a eclipse

[Jookyn]

Mam problém s instalovánim některejch java věcí. Mam nainstalovanou JDK 1.5 i 1.4 od Sunu, jako výchozí VM je 1.5. Při kompilaci např. dev-java/commons-net (jde mi hlavně o eclipse (verze 3.2 - testing)) to ale vůbec nedojede, hodí to chybu. java-check-environment proběhne v pořádku, všechno je ok. Celej výpis instalace přikládam.

Zkoušel jsem i předtim i blackdown, ale je to stejný... pravděpodobně jde ale o to, že commons-net potřebujou na kompilaci generation 1, tak se to přepne, ale pak je potřeba v tom něco překompilovat v generation 2. Nevíte někdo, jak to vyřešit?

Problem je v tom, ze pri kompilacii volas javu z JDK 1.4 a potrebujes volat JDK 1.5 (mas tam uz kniznice skompilovane v 1.5 - jcraft)

Skus si nastavit premennu PATH tak, aby prikaz

> java -version

vratil java 1.5....

Tak už to mam, java -version vrátí 1.5, to co je jako výchozí system VM. Ale na začátku emerge se to právě přepne do 1.4 a to je asi ten problém...
