  Inclusive jet production cross-sections are measured in proton--proton
collisions at a centre-of-mass energy of $\sqrt{s}=$8 TeV recorded by the ATLAS
experiment at the Large Hadron Collider at CERN. The total integrated
luminosity of the analysed data set amounts to $20.2$ fb$^{-1}$.
Double-differential cross-sections are measured for jets defined by the
anti-$k_{t}$ jet clustering algorithm with radius parameters of $R=0.4$ and
$R=0.6$ and are presented as a function of the jet transverse momentum, in the
range between 70 GeV and 2.5 TeV and in six bins of the absolute jet rapidity,
between 0 and 3.0. The measured cross-sections are compared to predictions of
quantum chromodynamics, calculated at next-to-leading order in perturbation
theory, and corrected for non-perturbative and electroweak effects. The level
of agreement with predictions, using a selection of different parton
distribution functions for the proton, is quantified. Tensions between the data
and the theory predictions are observed.
