  "message": "playground: use Go 1.12\n\nGo 1.12 has been released¹ and should be used, so that it\u0027s possible\nto play with Go programs that rely on Go 1.12-only features.\n\nIn Go 1.12, build cache is required. Either GOCACHE must be set,\nor HOME must be set so that GOCACHE can be implicitly deduced.\nSet HOME and pass it on to the go build invocation inside the\ncompileAndRun function.\n\nThis fixes the following error, detected by the playground test:\n\n\t2019/02/26 06:28:44 compile error: build cache is required, but could not\n\tbe located: GOCACHE is not defined and neither $XDG_CACHE_HOME nor $HOME\n\tare defined\n\tThe command \u0027/bin/sh -c /app/playground test\u0027 returned a non-zero code: 1\n\nThis is related to issues golang/go#29243 and golang/go#29251,\nand the fix in CL 154181.\n\n¹ https://groups.google.com/d/msg/golang-announce/Y1RZqnCKUKY/N9yK5c8iBgAJ\n\nFixes golang/go#30397\n\nChange-Id: I44c5c8928060732f31fd935b114568258c7298c7\nReviewed-on: https://go-review.googlesource.com/c/163798\nReviewed-by: Brad Fitzpatrick \u003cbradfitz@golang.org\u003e\n",
