Java - Instalación Eclipse en Centos 7

Buenos días, no he podido instalar Netbeans y ahora no puedo instalar Eclipse, estoy usando en un servidor con Centos 7. Agradeceré su gran apoyo porque me encuentro detenida en dicho proceso. El servidor en el que me encuentro trabajando es un servidor web con Joomla, con java instalado:

# java -version
openjdk version "1.8.0_191"
OpenJDK Runtime Environment (build 1.8.0_191-b12)
OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode)

Sin embargo al instalar eclipse envía el siguiente error:

Reintenta la instalación por si es un fallo temporal. Prueba en un navegador en la misma máquina a ver si puedes descargarte ese fichero o también te da algún error.
