构建RxJava项目失败的原因可能是以下异常？

jacek:~/oss/RxJava
$ ./gradlew build -x test
...
:rxjava-contrib:rxjava-android:compileJava
Download http://repo1.maven.org/maven2/xerces/xmlParserAPIs/2.6.2/xmlParserAPIs-2.6.2.pom
Download http://repo1.maven.org/maven2/xerces/xmlParserAPIs/2.6.2/xmlParserAPIs-2.6.2.jar

FAILURE: Build failed with an exception.

* What went wrong:
Could not resolve all dependencies for configuration ':rxjava-contrib:rxjava-android:provided'.
> Could not download artifact 'org.apache.maven:maven-error-diagnostics:2.2.1@jar'
   > Artifact 'org.apache.maven:maven-error-diagnostics:2.2.1@jar' not found.

Answer 1

当您看到错误时，您~/.m2/repository最有可能包含部分解决的依赖关系（在这种情况下，它是org.apache.maven:maven-error-diagnostics:2.2.1@jar）：

$ ls ~/.m2/repository/org/apache/maven/maven-error-diagnostics/2.2.1/
_maven.repositories                     maven-error-diagnostics-2.2.1.pom       maven-error-diagnostics-2.2.1.pom.sha1

只需从~/.m2/repository ...

中删除相关性目录

$ rm -rf ~/.m2/repository/org/apache/maven/maven-error-diagnostics/2.2.1/

...并重新运行构建。它现在应该建立良好。

jacek:~/oss/RxJava
$ ./gradlew build -x test
...
:rxjava-contrib:rxjava-swing:build

Answer 2

看起来您的本地maven缓存已损坏。清洁如下：

rm -rf ~/.m2

FAILURE：由于在构建RxJava时无法下载工件，构建失败并出现异常
