TYPO3 Core

As far as I understand Sebastian on Slack, he uses a composer distribution without class loading information in root composer.json

With the new class loader change this has become mandatory.

We might improve the situation here, but for now this is how it is.

specify a autoload section in your root composer.json like that:

    "autoload": {
        "psr-4": {
            "TYPO3\\CMS\\About\\": "typo3_src/typo3/sysext/about/Classes/",
            "TYPO3\\CMS\\Aboutmodules\\": "typo3_src/typo3/sysext/aboutmodules/Classes/",
            "TYPO3\\CMS\\Filelist\\": "typo3_src/typo3/sysext/filelist/Classes/",
            "TYPO3\\CMS\\Form\\": "typo3_src/typo3/sysext/form/Classes/",
            "TYPO3\\CMS\\Impexp\\": "typo3_src/typo3/sysext/impexp/Classes/",
            "TYPO3\\CMS\\Rsaauth\\": "typo3_src/typo3/sysext/rsaauth/Classes/",
            "TYPO3\\CMS\\Rtehtmlarea\\": "typo3_src/typo3/sysext/rtehtmlarea/Classes/",
            "TYPO3\\CMS\\SysNote\\": "typo3_src/typo3/sysext/sys_note/Classes/",
            "TYPO3\\CMS\\T3editor\\": "typo3_src/typo3/sysext/t3editor/Classes/",
            "TYPO3\\CMS\\T3skin\\": "typo3_src/typo3/sysext/t3skin/Classes/",
            "TYPO3\\CMS\\CssStyledContent\\": "typo3/sysext/css_styled_content/Classes/" 
        },
        "classmap": ["typo3conf/ext/realurl/"]
    },
