<p>Hi Matthias,<span style="mso-fareast-language:#2000"><o:p></o:p></span></p>
<p>Let me see if I get this correct. You got a build failure, and the built-in system could not diagnose it. Instead, it suggested that you should search the build log for
<span lang="en-DE">'] Error'. Instead, of doing this, you scrolled through the entire log, just to find that the actual error message was printed close to '] Error'..?</span><o:p></o:p></p>
<p><span lang="en-DE">What exactly are we to do about this?</span><o:p></o:p></p>
<p><span lang="en-DE">The reason we do not extract this information to the build failure summary is that it is not possible (or, if possible, extremely non-trivial). Instead, we direct the user on how to best go ahead to try and find this information themselves.
Fixing users not reading or following suggestions is unfortunately out of scope for the build system. ;-)</span><o:p></o:p></p>
<p><span lang="en-DE">There is no point in trying to search for this particular error and repeat it to the user. The "No indication of failed target found. Try searching the build log for '] Error'." is our generic fallback when we have no way to determine
the cause of failure. There are a myriad ways of the build to fail in that case, if we start adding special cases to this, there will be no end.</span><o:p></o:p></p>
